The 2023 Turkish Basketball Cup (Turkish: 2023 Basketbol Erkekler Türkiye Kupası), also known as Bitci Erkekler Türkiye Kupası for sponsorship reasons, is the 37th edition of Turkey's top-tier level professional national domestic basketball cup competition. The quarterfinals of the tournament were originally scheduled to be held on February 14–15, 2023 in 4 different locations and then the semi-finals and the final on February 17–19, 2023, respectively, in the Selçuklu Belediyesi Spor Salonu in Konya, Turkey. However, on 7 February 2023, the Turkish Basketball Federation announced that the competition was suspended indefinitely, after the 2023 Turkey–Syria earthquake.

The top eight placed teams after the first half of the top-tier level Basketball Super League 2022–23 season qualified for the tournament. The four highest-placed teams are going to play against the lowest-seeded teams in the quarter-finals. The competition will be played under a single elimination format.

The 2023 Turkish Basketball Cup was drawn on January 23, 2023. The seeded teams were paired in the quarterfinals with the non-seeded teams.
