The Sukhoi Su-31 is a Russian single-engined aerobatic aircraft designed by Sukhoi as a lighter and more powerful version of the Sukhoi Su-29.

The design of the aircraft started in 1991 as a single-seat development of the earlier Sukhoi Su-29 with a more powerful Vedeneyev M14PF engine and new landing gear. The low-wing cantilever monoplane first flew in June 1992 as the Su-29T and the first production aircraft flying in 1994.
