The Beşiktaş-Fenerbahçe rivalry are the basketball (men's and women's) matches between Beşiktaş and Fenerbahçe, two clubs representing the city of Istanbul.

Beşiktaş's men's basketball department were founded in 1933, before being halted in 1936, and then resuming once again in 1940.

The club won the Turkish Super League, under the management of Ateş Çubukçu and Tom Davis, in the 1974–75 season.

The men's basketball department of Fenerbahçe were founded in 1913 and achieved considerable success when the sport established itself in Turkey.

Fenerbahçe won national championship titles in 1957, 1959 and 1965, just before the Turkish League was founded in 1966, and participated in the European Champions Cup in 1960 and 1966.
