The Subaru 360 is a rear-engined, two-door city car manufactured and marketed from 1958 to 1971 by Subaru. As the company's first automobile, production reached 392,000 over its 12-year model run.

Noted for its small overall size, 1,000 lb curb weight, monocoque construction, swing axle rear suspension, fiberglass roof panel, and rear-hinged doors, the inexpensive car was designed in response to the Japanese government's light car or Kei car regulations and its proposal for a larger "national car," both intended to help motorize the post WWII Japanese population. The 360's overall size and engine capacity complied with Japan's Kei car regulations.

Nicknamed the "ladybug" in Japan, and ultimately superseded by R-2, the 360 was one of Japan's most popular cars and was available in a single generation in two-door, station wagon ("Custom"), "convertible" (a sedan with a roll-back fabric roof) and sporting variants. The two-door sedans' model code is K111, while the wagon is known as K142. Ten thousand were sold in the United States, imported by Malcolm Bricklin and advertised as "Cheap and Ugly."
