The Basketbol Süper Ligi (BSL) is the top-tier level pre-eminent professional men's club basketball league in Turkey. In English, it is known as the Turkish Basketball Super League (Turkish: Türkiye Basketbol Süper Ligi). The league was previously known as the Turkish Basketball League (TBL).
There is also a second-tier level Turkish Basketball First League (TBL) with 18 teams, and since 2011, a third-tier level Turkish Basketball Second League (TB2L), with the teams divided into two groups.
According to the official records, in Turkey, basketball was first played in 1904 at Robert College. An American physical education teacher laid the foundations of this sport in Turkey. 7 years later, Ahmet Robenson, a physical education teacher at Galatasaray High School decided to introduce a new game to the students in 1911. Robenson who also became a Galatasaray S.K. president later, popularized this sport in Turkey.
Until late 1966, local basketball competitions were being held in big cities like Istanbul, Ankara and İzmir. The national league was founded in 1966 by the Turkish Basketball Federation, and began with the 1966–67 season. The TB2L was also founded three years later.
There are 16 teams in the league and they play against each other twice in the league manner, once at their home and the other away. At the end of the season, the top eight teams are entitled to participate in the Play-offs. The winner of the play-offs is crowned the Turkish national champion.
