The Sultan Mehmed Fatih Mosque of Krujë (Albanian: Xhamia e Sulltan Mehmed Fatihut) or Fethiye Mosque (Albanian: Xhamia e Fet'hijes) is an Ottoman-era mosque built before 1481 inside the Krujë Castle of Krujë, Durrës County, Albania. It is near the entrance of the Skanderbeg Museum.
The Sultan Mehmed Fatih Mosque was built before 1481 and named after the Ottoman Sultan Mehmed II (also called "the Conqueror"). After being destroyed in 1831, the mosque got rebuilt for the local Albanian population under the reign of the Sultan Mahmud II.
In 1917, the minaret of the Sultan Mehmed Fatih Mosque, famed for its beauty, collapsed due to a storm. Until 1937, the mosque was used a house of worship for the Albanian Muslims. During the Second World War, the mosque was abused and ammunition was stored inside the mosque. The mosque again decayed during the time of the Communist dictator Enver Hoxha.
Today, only the lower parts of the walls and the minaret remain of the Sultan Mehmed Fatih Mosque.
