Reipas Lahti is a sports club based in Lahti, Finland. It is involved in various of ball games and also other sports. The club emerged in the late 1940s, when the inhabitants of Viipuri had mostly been relocated in Lahti, after evacuation during World War II. As a consequence, the activities of Viipurin Reipas, which had been founded in 1891, were continued in the new home town of the evacuees. The name of the club was still Reipas Viipuri until 1962, when the ball game section became simply Reipas.
