The Continental O-190 (Company designations C75 and C85) is a series of engines made by Continental Motors beginning in the 1940s. Of flat-4 configuration, the engines produced 75 hp (56 kW) or 85 hp (63 kW) respectively.^[1]

The two variants shared the same bore, stroke and compression ratio. The C-85 produced ten extra horsepower by virtue of having a maximum permissible rpm of 2575 versus the 2275 of the C75.^[1]

The C75 was in production from 1943 to 1952 and the C85 from 1944 to 1970.
