Bîc (also spelled Bâc, pronunciation: [bɨk]) is a river in Moldova, a right tributary of the Dniester.

As it flows west and south, the upper Bâc cuts a deep canyon in the Codri Hills.

After departing Chișinău, it flows further south and west through the town of Anenii Noi, and then empties into the Dnistr near the village of Gura Bîcului ("mouth of the Bîc").

Rock formations in the Codri Hills are said to be the remains of a wall built by devils in an unsuccessful attempt to dam the river.

The Bâc was never navigable above Anenii Noi, but it was an important source of water and fish for local communities.

Industries and private enterprises dump wastewater into it, and as it flows through Chișinău it receives large amounts of untreated runoff.
