The an-Nāranj Pool (Arabic: بركة النارنج Birkat an-Nāranj, lit. 'pond of the bitter orange') is a small pool in the al-Aqsa Mosque Compound. It is at the compound's western esplanade, between the Fountain of Qasim Pasha (Sabil an-Nāranj) and the Fountain of Qayt Bay (to its south).

It was also known as al-Rāranj (الرارنج) and al-Ghāghanj (الغاغنج); both are phonetic variations of an-Nāranj.

It was built in the Ottoman period. It was restored during the reign of Sultan Qaitbay and again in 1527 by Qasim Pasha, a governor of Jerusalem. In 1922, the Supreme Muslim Council reconstructed the pool, paved it with marble and encircled it with banisters. The pool is seven metres wide.
