The DBB Albert Schweitzer Tournament (German: Albert-Schweitzer-Turnier, abbreviated as AST), full name DBB Albert Schweitzer World Under-18 Tournament (German: DBB Albert Schweitzer Welt-Unter-18-Turnier), is an international basketball competition that is played between national teams of the Under-18 men's age category. It takes place every two years in Mannheim, Germany, and is contested between teams from 12 countries.
The organizers of the tournament are the German Basketball Federation (German: Deutscher Basketball Bund, abbreviated as DBB), and the city of Mannheim. The tournament is named after Albert Schweitzer. Since FIBA does not organize an Under-18 world championship, the Albert Schweitzer Tournament is internationally recognized and considered an official non-FIBA organized world championship for the Under-18 age group. From 1958 to 1993, the tournament was an Under-19 age competition. Since 1994, it has been an under-18 age competition.
