Baltit Fort (Urdu: قلعہ بلتت) is a fort in the Hunza valley, near the town of Karimabad, in the Gilgit-Baltistan region of northern Pakistan. Founded in the 8th century CE, it has been on the UNESCO World Heritage Tentative list since 2004.

The Mirs of Hunza abandoned the fort in 1945, and moved to a new palace down the hill. The fort started to decay which caused concern that it might possibly fall into ruin. Following a survey by the Royal Geographical Society of London a restoration programme was initiated and supported by the Aga Khan Trust for Culture Historic Cities Support Programme. The programme was completed in 1996 and the fort is now a museum run by the Baltit Heritage Trust.
