Bâc (also spelled Bîc) is a river in Moldova, a right tributary of Dniester.
The upper flow of Bâc cuts a deep canyon in Codri Hills. The capital of Moldova, Chișinău, is situated near Bâc. A dam near Chișinău holds the Chișinău Sea reservoir, which has an area of about 10 km². During the summer season, Bâc often dries out and turns into a chain of lakes. The river is heavily polluted, so swimming in it is not advisable.
