There are 38 subspecies of Canis lupus listed in the taxonomic authority Mammal Species of the World (2005, 3rd edition). These subspecies were named over the past 250 years, and since their naming, a number of them have gone extinct. The nominate subspecies is the Eurasian wolf (Canis lupus lupus).

Taxonomy

In 1758, the Swedish botanist and zoologist Carl Linnaeus published in his Systema Naturae the binomial nomenclature – or the two-word naming – of species. Canis is the Latin word meaning "dog",{{OEtymD|canine}} and under this genus he listed the dog-like carnivores including domestic dogs, wolves, and jackals. He classified the domestic dog as Canis familiaris, and on the next page he classified the wolf as Canis lupus.{{cite book|last=Linnæus|first=Carl|title=Systema naturæ per regna tria naturæ, secundum classes, ordines, genera, species, cum characteribus, differentiis, synonymis, locis. Tomus I|year=1758|publisher=Laurentius Salvius|location=Holmiæ (Stockholm)|pages=39–40|url=https://www.biodiversitylibrary.org/item/80764#page/49/mode/1up|edition= 10th|access-date=November 23, 2012|language=la}} Linnaeus considered the dog to be a separate species from the wolf because of its head, body, and cauda recurvata – its upturning tail – which is not found in any other canid.

In 1999, a study of mitochondrial DNA indicated that the domestic dog may have originated from multiple wolf populations, with the dingo and New Guinea singing dog "breeds" having developed at a time when human populations were more isolated from each other. In the third edition of Mammal Species of the World published in 2005, the mammalogist W. Christopher Wozencraft listed under the wolf Canis lupus some 36 wild subspecies, and proposed two additional subspecies: familiaris Linnaeus, 1758 and dingo Meyer, 1793. Wozencraft included hallstromi – the New Guinea singing dog – as a taxonomic synonym for the dingo. Wozencraft referred to the mDNA study as one of the guides in forming his decision, and listed the 38 subspecies under the biological common name of "wolf", with the nominate subspecies being the Eurasian wolf (Canis lupus lupus) based on the type specimen that Linnaeus studied in Sweden. However, the classification of several of these canines as either species or subspecies has recently{{when|date=July 2024}} been challenged.

List of extant subspecies

Living subspecies recognized by MSW3 {{As of|2005|lc=on}} and divided into Old World and New World:

=Eurasia and Australasia=

Sokolov and Rossolimo (1985) recognised nine Old World subspecies of wolf. These were C. l. lupus, C. l. albus, C. l. pallipes, C. l. cubanenesis, C. l. campestris, C. l. chanco, C. l. desertorum, C. l. hattai, and C. l. hodophilax. In his 1995 statistical analysis of skull morphometrics, mammalogist Robert Nowak recognized the first four of those subspecies, synonymized campestris, chanco and desertorum with C. l. lupus, but did not examine the two Japanese subspecies. In addition, he recognized C. l. communis as a subspecies distinct from C. l. lupus. In 2003, Nowak also recognized the distinctiveness of Arabian wolf, C. l. hattai, C. l. italicus, and C. l. hodophilax.{{Harvnb|Nowak|2003|pp=245–246}} In 2005, MSW3 included C. l. filchneri. In 2003, two forms were distinguished in southern China and Inner Mongolia as being separate from C. l. chanco and C. l. filchneri and have yet to be named.

For North America, in 1944 the zoologist Edward Goldman recognized as many as 23 subspecies based on morphology.{{cite book|last1=Young|first1=Stanley P.|last2=Goldman|first2=Edward A.|title=The Wolves of North America|publisher=Dover Publications, New York|volume=2|year=1944|pages=413–477|isbn=978-0486211930}} In 1959, E. Raymond Hall proposed that there had been 24 subspecies of lupus in North America.The Mammals of North America, E. Raymond Hall & Keith R. Kelson, Ronald Press New York, 1959 In 1970, L. David Mech proposed that there was "probably far too many subspecific designations...in use", as most did not exhibit enough points of differentiation to be classified as separate subspecies.Mech, L. David. 1970. The Wolf: The Ecology and Behavior of an Endangered Species. University of Minnesota Press, Minneapolis The 24 subspecies were accepted by many authorities in 1981 and these were based on morphological or geographical differences, or a unique history.The Mammals of North America, E. Raymond Hall, Wiley New York, 1981 In 1995, the American mammalogist Robert M. Nowak analyzed data on the skull morphology of wolf specimens from around the world. For North America, he proposed that there were only five subspecies of the wolf. These include a large-toothed Arctic wolf named C. l. arctos, a large wolf from Alaska and western Canada named C. l. occidentalis, a small wolf from southeastern Canada named C. l. lycaon, a small wolf from the southwestern U.S. named C. l. baileyi and a moderate-sized wolf that was originally found from Texas to Hudson Bay and from Oregon to Newfoundland named C. l. nubilus.

The taxonomic classification of Canis lupus in Mammal Species of the World (3rd edition, 2005) listed 27 subspecies of North American wolf, corresponding to the 24 Canis lupus subspecies and the three Canis rufus subspecies of Hall (1981). The table below shows the extant subspecies, with the extinct ones listed in the following section.

| Two forms are known – a small, reddish-brown colored form called the Algonquin wolf; and a slightly larger, more grayish-brown form called the Great Lakes wolf, which is an admixture of the Algonquin wolf and other gray wolves.Young, Stanley P.; Goldman, Edward A. (1944). The Wolves of North America, Part II. New York, Dover Publications, Inc., pp. 437-41

| The Algonquin form occupies central Ontario and southwestern Quebec, particularly in and nearby protected areas, such as Algonquin Provincial Park in Ontario, and possibly extreme northeastern U.S. and western New Brunswick. The Great Lakes form occupies northern Ontario, Wisconsin and Minnesota, the Upper Peninsula of Michigan and southern Manitoba. Overlaps of the two forms occur, with intermixing in the southern portions of northern Ontario.

==Italian wolf==

{{Further|Italian wolf}}

The Italian wolf (or Apennine wolf) was first recognised as a distinct subspecies (Canis lupus italicus) in 1921 by zoologist Giuseppe Altobello.{{in lang|it}} Altobello, G. (1921), [http://www.storiadellafauna.it/scaffale/testi/alto/Carnivo.htm Fauna dell'Abruzzo e del Molise. Mammiferi. IV. I Carnivori (Carnivora)] {{Webarchive|url=https://web.archive.org/web/20160504133849/http://www.storiadellafauna.it/scaffale/testi/alto/Carnivo.htm |date=2016-05-04 }}, Colitti e Figlio, Campobasso, pp. 38-45 Altobello's classification was later rejected by several authors, including Reginald Innes Pocock, who synonymised C. l. italicus with C. l. lupus.{{cite journal | last1 = Nowak | first1 = R.

Nowak reaffirmed the morphological distinctiveness of the Italian wolf and recommended the recognition of Canis lupus italicus. A number of DNA studies have found the Italian wolf to be genetically distinct.{{Cite journal | doi = 10.1046/j.1523-1739.1992.06040559.x| title = Mitochondrial DNA Variability of the Gray Wolf: Genetic Consequences of Population Decline and Habitat Fragmentation| journal = Conservation Biology| volume = 6| issue = #4| pages = 559–569| year = 1992| last1 = Wayne | first1 = R.

This population also showed a unique mitochondrial DNA control-region haplotype, the absence of private alleles and lower heterozygosity at microsatellite loci, as compared to other wolf populations.V. LUCCHINI, A. GALOV and E. RANDI Evidence of genetic distinction and long-term population decline in wolves (Canis lupus) in the Italian Apennines. Molecular Ecology (2004) 13, 523–536. [https://archive.today/20120604094904/http://www3.interscience.wiley.com/journal/118794860/abstract abstract online] In 2010, a genetic analysis indicated that a single wolf haplotype (w22) unique to the Apennine Peninsula and one of the two haplotypes (w24, w25), unique to the Iberian Peninsula, belonged to the same haplogroup as the prehistoric wolves of Europe. Another haplotype (w10) was found to be common to the Iberian peninsula and the Balkans. These three populations with geographic isolation exhibited a near lack of gene flow and spatially correspond to three glacial refugia.

The taxonomic reference Mammal Species of the World (3rd edition, 2005) does not recognize Canis lupus italicus; however, NCBI/Genbank publishes research papers under that name.{{cite web|title=NCBI search Canis lupus italicus|url=https://pubmed.ncbi.nlm.nih.gov/?term=canis+lupus+italicus}}

==Iberian wolf==

{{Further|Iberian wolf}}

The Iberian wolf was first recognised as a distinct subspecies (Canis lupus signatus) in 1907 by zoologist Ángel Cabrera. The wolves of the Iberian peninsula have morphologically distinct features from other Eurasian wolves and each are considered by their researchers to represent their own subspecies.{{cite web| url = http://www.signatus.org/docs/situation.pdf| title = The wolf in Spain}}{{cite journal |doi=10.1111/j.1469-7998.2000.tb00801.x|title=Food habits and livestock depredation of two Iberian wolf packs (Canis lupus signatus) in the north of Portugal|journal=Journal of Zoology|volume=251|issue=#4|pages=457–462|year=2000 |last1=Vos|first1=J.}}

The Himalayan wolf is distinguished by its mitochondrial DNA, which is basal to all other wolves. The taxonomic name of this wolf is disputed, with the species Canis himalayensis being proposed based on two limited DNA studies. In 2017, a study of mitochondrial DNA, X-chromosome (maternal lineage) markers and Y-chromosome (male lineage) markers found that the Himalayan wolf was genetically basal to the Holarctic grey wolf and has an association with the African golden wolf.

In 2019, a workshop hosted by the IUCN/SSC Canid Specialist Group noted that the Himalayan wolf's distribution included the Himalayan range and the Tibetan Plateau. The group recommends that this wolf lineage be known as the "Himalayan wolf" and classified as Canis lupus chanco until a genetic analysis of the holotypes is available. In 2020, further research on the Himalayan wolf found that it warranted species-level recognition under the Unified Species Concept, the Differential Fitness Species Concept, and the Biological Species Concept. It was identified as an Evolutionary Significant Unit that warranted assignment onto the IUCN Red List for its protection.{{cite journal|doi=10.1111/jbi.13824|title=Himalayan wolf distribution and admixture based on multiple genetic markers|year=2020|last1=Werhahn|first1=Geraldine|last2=Liu|first2=Yanjiang|last3=Meng|first3=Yao|last4=Cheng|first4=Chen|last5=Lu|first5=Zhi|last6=Atzeni|first6=Luciano|last7=Deng|first7=Zhixiong|last8=Kun|first8=Shi|last9=Shao|first9=Xinning|last10=Lu|first10=Qi|last11=Joshi|first11=Jyoti|last12=Man Sherchan|first12=Adarsh|last13=Karmacharya|first13=Dibesh|last14=Kumari Chaudhary|first14=Hemanta|last15=Kusi|first15=Naresh|last16=Weckworth|first16=Byron|last17=Kachel|first17=Shannon|last18=Rosen|first18=Tatjana|last19=Kubanychbekov|first19=Zairbek|last20=Karimov|first20=Khalil|last21=Kaden|first21=Jennifer|last22=Ghazali|first22=Muhammad|last23=MacDonald|first23=David W.|last24=Sillero-Zubiri|first24=Claudio|last25=Senn|first25=Helen|journal=Journal of Biogeography|volume=47|issue=6|pages=1272–1285|doi-access=free|bibcode=2020JBiog..47.1272W }}

==Indian plains wolf==

{{Further|Indian wolf#Canis indica}}

The Indian plains wolf is a proposed clade within the Indian wolf (Canis lupus pallipes) that is distinguished by its mitochondrial DNA, which is basal to all other wolves except for the Himalayan wolf. The taxonomic status of this wolf clade is disputed, with the separate species Canis indica being proposed based on two limited DNA studies. The proposal has not been endorsed because it relied on a limited number of museum and zoo samples that may not have been representative of the wild population, and a call for further fieldwork has been made.

The taxonomic reference Mammal Species of the World (3rd edition, 2005) does not recognize Canis indica; however, NCBI/Genbank lists it as a new subspecies, Canis lupus indica.{{cite web|title=Canis lupus indica|url=https://www.ncbi.nlm.nih.gov/Taxonomy/Browser/wwwtax.cgi?id=242524}}

==Southern Chinese wolf==

In 2017, a comprehensive study found that the gray wolf was present across all of mainland China, both in the past and today. It exists in southern China, which refutes claims made by some researchers in the Western world that the wolf had never existed in southern China. This wolf has not been taxonomically classified.

In 2019, a genomic study on the wolves of China included museum specimens of wolves from southern China that were collected between 1963 and 1988. The wolves in the study formed three clades: northern Asian wolves that included those from northern China and eastern Russia, Himalayan wolves from the Tibetan Plateau, and a unique population from southern China. One specimen from Zhejiang Province in eastern China shared gene flow with the wolves from southern China; however, its genome was 12–14 percent admixed with a canid that may be the dhole or an unknown canid that predates the genetic divergence of the dhole. The wolf population from southern China is believed to still exist in that region.

=North America=

==Coastal wolves==

A study of the three coastal wolves indicates a close phylogenetic relationship across regions that are geographically and ecologically contiguous, and the study proposed that Canis lupus ligoni (the Alexander Archipelago wolf), Canis lupus columbianus (the British Columbian wolf), and Canis lupus crassodon (the Vancouver Coastal Sea wolf) should be recognized as a single subspecies of Canis lupus, synonymized as Canis lupus crassodon. They share the same habitat and prey species, and form one study's six identified North American ecotypes – a genetically and ecologically distinct population separated from other populations by their different types of habitat.

==Eastern wolf==

{{Further|Eastern wolf}}

The eastern wolf has two proposals over its origin. One is that the eastern wolf is a distinct species (C. lycaon) that evolved in North America, as opposed to the gray wolf that evolved in the Old World, and is related to the red wolf. The other is that it is derived from admixture between gray wolves, which inhabited the Great Lakes area and coyotes, forming a hybrid that was classified as a distinct species by mistake.

The taxonomic reference Mammal Species of the World (3rd edition, 2005) does not recognize Canis lycaon; however, NCBI/Genbank does list it.{{cite web|title=Canis lycaon|url=https://www.ncbi.nlm.nih.gov/Taxonomy/Browser/wwwtax.cgi?id=228401}} In 2021, the American Society of Mammalogists also considered Canis lycaon a valid species.{{BioRef|asm|id=1005944|title=Canis lycaon |version=1.5 |access-date=17 September 2021}}

==Red wolf==

{{Further|Red wolf}}

The red wolf is an enigmatic taxon, of which there are two proposals over its origin. One is that the red wolf is a distinct species (C. rufus) that has undergone human-influenced admixture with coyotes. The other is that it was never a distinct species but was derived from past admixture between coyotes and gray wolves, due to the gray wolf population being eliminated by humans.{{cite journal|doi=10.1111/mec.13642|pmid=27064931|title=Hybridization and endangered species protection in the molecular era|journal=Molecular Ecology|volume=25|issue=#11|pages=2680–9|year=2016|last1=Wayne|first1=Robert K.|last2=Shaffer|first2=H.
