The Tahtakale Hamam is a historic Ottoman hammam building in Istanbul, Turkey, close to the Rüstem Pasha Mosque in the Tahtakale neighbourhood, between the Grand Bazaar and Eminönü. Built during the reign of Sultan Mehmet II, it is one of the oldest surviving bathhouses in the city. After having suffered significant damage while being used as a storage depot in the 20th century, the building was restored in the late 1980s and now serves as a local shopping centre and cafe.
