Christian Boussus (5 March 1908 – 12 August 2003)[7] was a left-handed French tennis player who found success in the 1920s and 1930s.

[8] He was the runner-up at the Pacific South-west Championship in 1928[9](lost to fellow Frenchman Henri Cochet) although he won the mixed title trophy alongside American Anna Harper.

[10] The same year he won his first outdoor doubles title in Düsseldorf pairing Davis Cup teammate Jean Borotra.

During World War II in 1941 in Vichy France, he won the unofficial French Open doubles title partnering Bernard Destremau, a feat that is unrecognized by the ITF.

In 1932, he and Marcel Bernard were defeated in the doubles finals of the French Championships by Henri Cochet and Jacques Brugnon.

[3][5][25] At the peak of his career in 1932 his play was observed by Great Britain's then active Davis Cup player Nigel Sharpe who described him as the greatest French left-hander in the following manner: "He relies upon an all-round game with volleying as his forte.

He gets good pace in this stroke and usually relies upon it as the forerunner of a volleying campaign[…]His backhand is of the cut variety but although putting so much slice on it he does not let it stop him from hitting it pretty hard.

[14] He had a brother Roland, also amateur tennis player, with whom he won the doubles title of the Le Touquet Spa Championships in 1937, while also winning the singles and mixed contest as well.
