Basler Sportclub Old Boys, commonly known as BSC Old Boys or Old Boys Basel, is a Swiss sports club based in Basel. The club is mainly known for its football but it also has track, swimming and tennis sections. The association's colors are yellow and black.
The club was founded as FC Old Boys Basel in 1894 but became BSC Old Boys at the beginning of the 20th century. In 1899, 1904 and 1912, the club finished runners-up in the Nationalliga A, but in 1932, the club was relegated from the professional leagues. After spending many years in the amateur leagues, Old Boys managed to climb back into the Nationalliga B in 1987, the same year that local rivals FC Basel were relegated from the Nationalliga A, meaning the two clubs would meet again. In the 1995/96 season, Old Boys were relegated again and they now play in the Second Group of Swiss 1. Liga.
BSC Old Boys play at the Stadium Schützenmatte, but the original home ground of the club was Margaret Meadow. The club had to move stadium because the IWB, the Industrial Works of Basel, moved there.
In 1922, a swimming section was founded, which later merged with other clubs, and in 1927, a tennis club was founded. In 1935, it split to become Tennis Club Old Boys, today's home club of Roger Federer.
