Nachvak Fjord is a deep fiord in northern Labrador nearly 2 km (1.2 mi) wide and 20 km (12 mi) long. The fjord is divided in two arms on the western end called Tallek and Tasiuyak. The Torngat Mountains that surround Nachvak Fjord are the highest in Labrador, where both Mount Razorback to the north and Mount Caubvick to the south are located.
