:List of Odonata species of Slovenia

Taxonomic order and nomenclature follow the Atlas of the European dragonflies and damselflies (2015), while Atlas of the Dragonflies (Odonata) of Slovenia is the primary source of the data, with notes explaining discrepancies.

Columns with scientific and vernacular names in English and Slovene are followed by conservation status as determined by the country's official Red list of Odonata (Rdeči seznam kačjih pastirjev).{{cite periodical |url=https://www.uradni-list.si/1/content?id=38615 |title=Pravilnik o uvrstitvi ogroženih rastlinskih in živalskih vrst v rdeči seznam |periodical=Uradni list Republike Slovenije |issue=82 |date=24 September 2002 |language=sl |access-date=23 October 2020 |archive-date=22 June 2016 |archive-url=https://web.archive.org/web/20160622170940/http://www.uradni-list.si/1/content?id=38615 |url-status=live }} - [https://www.uradni-list.si/files/RS_-2002-082-04055-OB~P021-0000.PDF Priloga 21: Rdeči seznam kačjih pastirjev (Odonata)] {{Webarchive|url=https://web.archive.org/web/20220617134038/https://www.uradni-list.si/files/RS_-2002-082-04055-OB~P021-0000.PDF |date=2022-06-17 }} Categories of conservation status according to this list are as follows:

• extinct species (EX): once reliably recorded native populations that have been exterminated in the past throughout the whole territory of the Republic of Slovenia.
• presumed extinct species (EX?): once reliably recorded native populations which haven't been seen for a longer period despite targeted searching, providing grounds for the presumption of local extinction.
• endangered species (E): the existence of this species on the territory of Slovenia is not likely in the future if the reasons for endangerment are not removed. Population size is critically low or is rapidly diminishing in a large part of the areal.
• vulnerable species (V): risk of becoming endangered (E) if the negative influences persist. Population size is being reduced in a large part of the areal, whereas the species is sensitive to changes in the environment or inhabits sensitive habitats.
• rare species (R): potentially vulnerable due to its rarity in Slovenia, may rapidly become endangered (E) in case of negative influences.
• non-defined (I): presumed endangered, but there is insufficient data to assign to any of the above categories.

Most (24) of the species included in the Red List are also protected according to the newer Ordinance on protected native species of animals (Uredba o zavarovanih prosto živečih živalskih vrstah) from 2004, which annulled the previous ordinance on which the Red list is based.{{cite periodical |url=http://www.uradni-list.si/1/objava.jsp?sop=2004-01-2216 |title=Uredba o zavarovanih prosto živečih živalskih vrstah |periodical=Uradni list Republike Slovenije |issue=46 |date=30 April 2004 }} - [http://pisrs.si/Pis.web/npb/2019-01-2803-2004-01-2216-npb10-p1.pdf Priloga 1: Seznam živalskih vrst, katerih živali so zavarovane] {{Webarchive|url=https://web.archive.org/web/20210719212644/http://pisrs.si/Pis.web/npb/2019-01-2803-2004-01-2216-npb10-p1.pdf |date=2021-07-19 }} The protected species are labelled with an additional asterisk (*), while the old Red list statuses are retained for reference.

Most species native to Slovenia are not globally threatened and are regarded least-concern by the International Union for Conservation of Nature (IUCN). There are two exceptions – both Cordulegaster species – that are near-threatened. Additionally, the southern damselfly (Coenagrion mercuriale) is near-threatened as well, but that species is almost certainly extirpated.

The Slovene Atlas mentions four additional species as records from older literature, but there is insufficient evidence for their presence so they are excluded from that list as well:

• Irish damselfly (Coenagrion lunulatum) – one recorded sighting in the 1950s, but Slovenia lies far outside the species' distribution range so it was most likely misidentified
• large pincertail (Onychogomphus uncatus) – one sighting with a photograph, but the specimen cannot be reliably distinguished from the similar Onychogomphus forcipatus in the picture
• golden-ringed dragonfly (Cordulegaster boltonii) – records from the 1950s belong to Cordulegaster heros which was formally split from C. boltonii in 1979
• northern white-faced darter (Leucorrhinia rubicunda) – one doubtful sighting
