Cycloderma is a genus of softshell turtles in the subfamily Cyclanorbinae of the family Trionychidae. The genus is endemic to Africa.

The genus Cycloderma contains the following extant species:

• Aubry's flapshell turtle – Cycloderma aubryi (A.H.A. Duméril, 1856)^[1]
• Zambezi flapshell turtle – Cycloderma frenatum W. Peters, 1854^[1]

Two extinct fossil species are also known: Cycloderma victoriae Andrews, 1914, from the early Miocene of Kenya; and Cycloderma debroinae Meylan et al., 1990, from the late Miocene to the Pliocene of Kenya.^[3][4]

Nota bene: A binomial authority in parentheses indicates that the species was originally described in a genus other than Cycloderma.
