Galatasaray Spor Kulübü (English: Galatasaray Sports Club) is a multi-sports club based in Istanbul, Turkey. The club was founded in 1905, by Ali Sami Yen and other students of Galatasaray High School. In the 1910s, water polo began to be played for the first time in Istanbul by Galatasaray fans.

With the arrival of Hungarian coach Zoltan Gulyas in 1988, importance was given to infrastructure works, and water polo started to become a branch of society that tries to train Olympic athletes instead of a branch that makes the children of its members to do sports.
