The CAMS 33 was a reconnaissance flying boat built in France in the early 1920s.

It was designed in response to a French Navy requirement for new flying boats for various roles.

The design was a conventional biplane flying boat with equal-span unstaggered wings and two engines mounted in a single nacelle in tractor-pusher configuration on struts in the interplane gap.

Twelve aircraft were eventually produced for the French Navy, these equipping Escadrille 1R1 at Cherbourg-Chantereyne.

The 33T prototype flew under civil registration for a few years, but was unable to attract customers.
