Faxonius Burri

''Faxonius'' is a genus of freshwater crayfish in the family Cambaridae. There are more than 90 described species in ''Faxonius''. It includes the rusty crayfish, an invasive species in North America, and three species, ''F. virilis'', ''F. immunis'', and ''F. limosus'', that are invasive to Europe.

This genus was formerly considered a subgenus of ''Orconectes''. Several former ''Orconectes'' species were added to this genus in 2017, leaving only the troglobite, cave dwelling species unchanged, however ''F. stygocaneyi'' was reallocated, even though it lives in caves.
