The Antonov A-13 was a Soviet aerobatic sailplane flown in the 1950s and 1960s. It was a small, single-seat, all-metal aircraft developed from the A-11 which could optionally be fitted with that aircraft's longer-span wings. It was a mid-wing monoplane with a tadpole-like fuselage and a V-tail.

In February 1962, an A-13 was fitted with a small turbojet engine to set a world airspeed record of 196 km/h (122 mph) for an aircraft weighing up to 500 kg. This jet-powered version was known as the An-13
