The Cessna 177 Cardinal is a light single-engine, high-wing general aviation aircraft that was intended to replace Cessna's 172 Skyhawk. First announced in 1967, it was produced from 1968 to 1978.

The Cessna 177 was designed in the mid-1960s when the engineers at Cessna were asked to create a "futuristic 1970s successor to the Cessna 172". The resulting aircraft featured newer technology such as a cantilever wing lacking the lift struts of previous models, and a new laminar flow airfoil. The 177 is the only production high-wing single-engined Cessna since the Cessna 190 & 195 series to have both fixed landing gear and a cantilever wing without strut bracing.

In 1971, Cessna experimented with a "Quiet Cardinal" similar to the Beechcraft QU-22 Pave Eagle. A test model was flown with a Wankel engine with a large three bladed 100 inch diameter propeller with a belt driven gear reduction unit and a fuselage-length exhaust canted upward.

The 1968 model 177 was introduced in late 1967 with a 150 hp (112 kW) engine. One of the design goals of this 172 replacement was to allow the pilot an unobstructed view when making a turn. In the 172 the pilot sits under the wing and when the wing is lowered to begin a turn that wing blocks the pilot's view of where the turn will lead to. The engineers resolved this problem by placing the pilot forward of the wing's leading edge, but that led to a too-far-forward center of gravity.

This problem was partially counteracted by the decision to use the significantly lighter Lycoming O-320 four-cylinder engine in place of the six-cylinder O-300 Continental used on the 172. The forward CG situation still existed even with the lighter engine, so a stabilator was chosen, to provide sufficient elevator control authority at low airspeeds.

The 177 design was intended to be a replacement for the 172, which was to be discontinued after introduction of the new aircraft. The new design was originally to be called the 172J (to follow the 1968 model 172I). However, as the time came to make the transition, there was considerable resistance to the replacement of the 172 from the company's Marketing Division. The 1969 172 jumped to the designator 172K—there is no 172J.
