The Scottish Aviation Twin Pioneer was a British STOL transport aircraft of the 1950s, designed with both civil and military operators in mind. It was conceived as a twin-engined version of the Pioneer light transport.

Powered by two Alvis Leonides engines, it was a high-wing cabin monoplane with a triple fin and rudder assembly and fixed tailwheel undercarriage.

The military version could carry external stores such as bombs under stub wings. It was used extensively by British forces in the Malayan Emergency and the later confrontation in Borneo.
