The Cessna 185, also known as the Skywagon, is a six seat, single engined, general aviation light aircraft manufactured by Cessna. It first flew as a prototype in July 1960, with the first production model being completed in March of 1961. The Cessna 185 is a high-winged aircraft with non-retractable conventional landing gear and a tailwheel. Over 4,400 were built with production ceasing in 1985. Production ceased in large part in 1985 due to two factors: the demise of the general aviation boom that characterized the post World War II years in the United States, and the growing awareness by insurance companies that tail wheel aircraft were harder to insure due to their handling characteristics during take off and landing. When Cessna re-introduced some of its most popular models in the 1990's, the tailwheel equipped Cessna 180 and 185 were left to the history books and not resurrected.

The aircraft is basically a Cessna 180 with a strengthened fuselage. The main difference between the two aircraft is the larger vertical fin on the 185 and the 300 hp (224 kW) Continental Motors IO-520-D engine as opposed to the 230 hp (172 kW) Continental Motors O-470-S fitted in the Cessna 180. The exception was that a Continental Motors IO-470-F engine of 260 hp (194 kW) was initially fitted until midway through the 1966 production year. The later model Skywagon II has a factory fitted avionics package.

The Skywagon can also be fitted with floats, amphibious float, or skis. The AGcarryall variant of the 185 adds a 151-gallon belly chemical tank and removable spray booms for aerial application. It is also possible to fit a cargo pod under the fuselage that can carry an extra 300 lb (136 kg).

The 180 and 185 are widely used in bush flying, the commercial transport of people and freight to remote austre airstrips and floatplane accessible lakes primarily in Canada and Alaska.

The ICAO designator as used in flight plans for the Cessna 185 is C185.
