Claes Cronqvist (born 15 October 1944) is a Swedish former footballer who played as a striker.

Claes Cronqvist began his career in Landskrona BoIS in 1962, and played in 1966–1970 for Djurgårdens IF and became a Swedish champion during his first year in his new club.

In 1971, he transferred back to Landskrona BoIS, where he won the Swedish cup in 1972 and two bronze medals for the seasons 1975 and 1976.

He continued with the club with a very weak start of the season and the second half of the 22-game league play improved.

The outcome would be decided by a penalty shootout at Landskrona IP; BoIS were victorious and returned to tier 2 of Swedish football in 1986.
