Neolithodes is a genus of king crabs in the subfamily Lithodinae.{{cite WoRMS|last=Ahyong|first=Shane T.|author-link=Shane T. Ahyong|date=12 December 2023|title=Neolithodes A. Milne-Edwards & Bouvier, 1894|id=106846|access-date=3 December 2024}} They are found in all major oceans, both in high and low latitudes. Although there are records from water as shallow as {{cvt|70|m|ft}} in cold regions, most records are much deeper, typically {{cvt|700-2000|m|ft|}}, with the deepest confirmed at {{cvt|5238|m|ft}}.{{Cite book|title=King Crabs of the World: Biology and Fisheries Management|publisher=CRC Press|year=2014|isbn=978-1-4398-5541-6|editor-last=Stevens|editor-first=Bradley G.|doi=10.1201/b16664|lccn=2013036692}}{{Page needed|date=May 2020}}{{Cite journal|last1=Quigley|first1=Declan T.

Interactions with other species
Various sessile organisms such as barnacles are sometimes attached to their carapace and legs,{{Cite journal|last1=Williams|first1=Ruth|last2=Moyse|first2=John|date=May 1988|title=Occurrence, Distribution, and Orientation of Poecilasma kaempferi Darwin (Cirripedia: Pedunculata) Epizoic on Neolithodes grimaldi Milne-edwards and Bouvier (Decapoda: Anomura) in the Northeast Atlantic|journal=Journal of Crustacean Biology|volume=8|issue=2|pages=177–186|doi=10.2307/1548310|jstor=1548310|bibcode=1988JCBio...8..177W }} and small commensal amphipods may live in their carapace.{{Cite journal|last1=Soto|first1=Luis A.|last2=Corona|first2=Adriana|date=31 December 2007|title=Gammaropsis (Podoceropsis) grasslei (Amphipoda: Photidae) a new species of commensal amphipod of the deep-water lithodid Neolithodes diomedeae from the Guaymas Basin, Gulf of California|journal=Zootaxa|volume=1406|pages=33–39|doi=10.5281/zenodo.175510}} They are occasionally the victims of parasitic snailfish of the genus Careproctus, which lay their egg mass in the gill chamber of the crab, forming a mobile "home" until they hatch. Conversely, some juvenile Neolithodes have a commensal relationship with Scotoplanes sea cucumbers. To protect itself from large predators, the young crab hides under the sea cucumber.{{Cite journal|last1=Barry|first1=James P.|last2=Taylor|first2=Josi R.|last3=Kuhnz|first3=Linda A.|last4=DeVogelaere|first4=Andrew P.|date=15 October 2016|title=Symbiosis between the holothurian Scotoplanes sp.

Taxonomy
The word Neolithodes derives from the Greek {{Transliteration|grc|neo}}, meaning new, and Lithodes, a closely related genus of king crab.{{sfn|Emmerson|2017|p=93}} The name of the latter genus originates from the Latin {{lang|la|lithodes}}, meaning stone like.{{sfn|Emmerson|2017|p=93}} No known Neolithodes fossils exist.{{sfn|Emmerson|2017|p=92}}
