The CAMS 53 was a transport flying boat built in France in the early 1930s intended as a successor to the highly successful CAMS 53. Compared to the earlier design, the CAMS 58 featured a newly-designed sesquiplane wing cellule and an all-metal hull in place of its predecessor's wooden one. Work was slow, with three years passing between the start of design work and the prototype's first flight. When the newly-formed Air France showed no interest in purchasing the type, CAMS redesigned it to be powered by two pairs of engines in tractor-pusher installations. Again, no interest was forthcoming. The final iteration of the design, reverting to a single pair of more powerful engines and a wooden hull, met with only slightly more success. Air France bought two machines and operated them briefly before declaring them to be uneconomical and removing them from service.
