Ctenochasmatidae is a group of pterosaurs within the suborder Pterodactyloidea.

The earliest known ctenochasmatid remains date to the Late Jurassic Kimmeridgian age. Previously, a fossil jaw recovered from the Middle Jurassic Stonesfield Slate formation in the United Kingdom, was considered the oldest known. This specimen supposedly represented a member of the family Ctenochasmatidae,[1] though further examination suggested it actually belonged to a teleosaurid stem-crocodilian instead of a pterosaur.[2]
