Trachelas is a genus of araneomorph spiders which has variously been placed in families Trachelidae or Corinnidae. Current taxonomy places it in Trachelidae.

Though the name was first used in an identification key published by Ludwig Carl Christian Koch in 1866, it did not include a description for either genders. In 1872, O. Pickard-Cambridge described the type species, ascribing it to the same name given several years earlier. Koch revisited the genus and covered it more thoroughly shortly after the type species was described.
