Costantino Rocca (born 4 December 1956) is an Italian golfer.
He was long known as the most successful male golfer that Italy has produced, until the 2018 success of Francesco Molinari, who credited Rocca as an inspiration to him following his Open victory.
After a long career on the European Tour, Constantino is now playing on the European Seniors Tour.
He has five European Tour wins and is best known for his second-place finish in the 1995 Open Championship, and his hole in one in 1995 Ryder Cup.
