The 1914–15 Istanbul Football League season was the 10th season of the league. Because of the high number of teams participating in the league and eventual disagreements among the clubs, there were two separate groups in that year. As a result there were two Istanbul champions at the end of the season. Galatasaray won the Istanbul Football Union League, while Fenerbahçe became champions in the Istanbul Championship League. According to most sources, including RSSSF, there was a final match between Fenerbahçe and Galatasaray on 11 February 1916, which Fenerbahçe won 3–1, and thus became the sole champions of the 1914–15 season.
