Karađoz Bey Mosque (Bosnian: Karađoz-begova džamija, Turkish: Karagöz Mehmed Bey Camii) is a 16th-century Ottoman mosque in the city of Mostar, Bosnia and Herzegovina.

An Arabic foundation inscription on the mosque records that it was commissioned by Mehmed Beg b. Abu al-Saʿadat’ who was a brother of a vizier in the year AH 965 (1557–58).

The outer portico has a shed roof resting on small octagonal pillars.

The large 10.65 metres (34.9 ft) dome of the mosque sits on an octagonal fenestrated drum which is supported by eight-pointed arches.

However, Karađoz Bey Mosque, like the rest of Mostar, underwent extensive repairs between 2002 and 2004.
