The PIK-13 was a sailplane constructed in Finland to compete in the 1954 World Gliding Championships, held at Camphill Farm, Great Hucklow, UK. It was a conventional mid-wing design of "workmanlike" construction and underwent five test flights in the course of 1954 before its entry in the competition.

In the championships, the PIK-13 was flown by Antti Koskisen, who was placed 16th with 931 points. The PIK-13 was destroyed in an accident on 26 March 1956 when the control stick broke in flight. Pilot Jorma Jalkanen parachuted to safety.
