Brasilennea is a fossil genus of small to medium-sized air-breathing land snails, terrestrial pulmonate gastropods in the family Cerionidae. The genus is known only from the Brazilian Paleocene Itaboraí Basin, in Rio de Janeiro.[3] The most characteristic feature of the genus is its two spiral furrows on the body whorl.[3]

The generic name Brasilennea originally intended to imply that it is a Brazilian genus that is very similar and related to the African genus Ennea.[2] This is no longer the case, however: while the genus was originally classified in the family Streptaxidae,[2] Brasilennea was then later transferred to the family Cerionidae.[3]
