The Daihatsu Midget is a single-seater mini-truck, later a microvan/kei truck made by Japanese automaker Daihatsu. Several distinct vehicles have borne the Midget name over the years, but all have had in common a single or two-seat utilitarian design, with an enclosed or semi-enclosed cab. Its appearance is very similar to the Cushman Truckster introduced in 1952. First generation (DK/DS/MP; 1957–1972) DK/DS series In August 1957 the original DKA Midget was introduced.

This model had already been sold in the United States since April 1959, as the MPA, although it was marketed as the "Daihatsu Trimobile". Companies such as Boeing and Lockheed used these little vehicles inside of their plants, for instance. The engine was the same (ZA) air-cooled two-stroke one-cylinder design with but an extra made for a sluggish vehicle. The DSA continued to be built alongside the more expensive MP variants into the early sixties. There was again a panel van version also available. Subsequent revisions to the MP design were soon made, resulting in the model MP3 which has the larger ZD engine of 305 cc which produced . In May 1960 the longer MP4 arrived, featuring roll-up door windows. In August 1961 the doors were modified, now incorporating a triangular vent window and a chromed side strip.
