Gerard Leembruggen (26 February 1897 – 13 May 1980), was a Dutch male tennis player who represented The Netherlands in the Davis Cup and the Olympic Games.
With compatriot Marius van der Feen he lost in the first round against the Czechoslovakian pair Ladislav Žemla and Jan Koželuh, also in straight sets.
In the doubles he teamed up with Bylandt (1924), Marinus van der Feen (1925, 1926) and Joop Knottenbelt (1934) but did not make it past the first round in four attempts.
His only participation in the mixed doubles, with Hilary Stebbing in 1924, also ended in the first round.
