The Crvena Zvezda–Partizan basketball rivalry, commonly referred as the Eternal derby (Serbian Cyrillic: Вечити дерби), is an Adriatic League, Serbian League, and Belgrade-based rivalry between Crvena zvezda and Partizan. These two men's basketball clubs are the biggest and most popular clubs in Serbia. The two clubs both play their home games at Aleksandar Nikolić Hall or Štark Arena in Belgrade. The rivalry started immediately after the creation of the two clubs in 1945 and the two clubs have been dominant in domestic basketball since then. It is present in a number of different sports but the most intense matches are in football sections of both clubs.
