Kenyonia is a genus or subgenus of sea snails, marine gastropod mollusks in the family Conidae, the cone snails and their allies.
In the new classification of the family Conidae by Puillandre N., Duda T.F., Meyer C., Olivera B.M. & Bouchet P. (2015), Kenyonia has become a subgenus of Conus: Conus (Kenyonia) Brazier, 1896 represented as Conus Thiele, 1929
In the same study it is also treated as genus incertae sedis within the family Conidae. In 1966 Powell suggested this was actually a turrid, and thought it to be synonym to Conopleura. A re-evaluation was made by an article in the malacological journal Nautilus by Donn L. Tippetl and John K. Tucker: Taxonomic Notes on Kenyonia Brazier and Conopleura Hinds (Gastropoda: Conoidea) and concluded to it belongs to the Conidae, based on the extensive interior re-modeling of the shell.
