Fagesia is a small, subglobular ammonite (suborder Ammonitina) belonging to the vascoceratid family of the Acanthocerataceae that lived during the Turonian stage of the Late Cretaceous, 92-88 Ma ago.

The shell of Fagesia is about 9.5 cm (3.47 in) in diameter, typically with blunt umbilical tubercles from which spring 2 or three ribs each, but which are lost in the late growth stage. The suture is ammonitic with long spikey lobes and saddles with rounded subelements.
