Balat is a neighbourhood in the municipality and district of Fatih, Istanbul Province, Turkey. Its population is 11,656 (2022). It is in the old city on the European side of Istanbul, on the western shore of the Golden Horn, sandwiched between Fener and Ayvansaray. Historically, it was the center of the Jewish community in Istanbul.

The name Balat is probably derived from Greek palation (palace), from Latin palatium, after the nearby Palace of Blachernae.

As in neighbouring Fener, Balat's back streets are lined with small stone two and three-storey terraced houses and a few grander mansions. In the 2020s, Balat become one of the hottest parts of the city for tourism, including domestic tourism, and many of the houses have been turned into cafes, restaurants and accommodation for visitors. Many of the houses have been repainted in bright colours to give a distinctive feel to the neighbourhood.

Balat is a stop on the T5 tramline connecting it to Cibali and the small bus terminal (for services to Anatolia) in Alibeyköy. The Golden Horn ferries also stop here, connecting Balat to Üsküdar, Karaköy, Kasımpaşa, Fener, Ayvansaray, Hasköy, Sütlüce and Eyüp.
