Brix (French pronunciation: [bʁi]) is a commune in the Manche department in Normandy in northwestern France.

[3] Brix is known primarily as being the assumed origin of the Bruce family, which emigrated to Britain in the Middle Ages and settled in northern England and then southern Scotland.

A family known variously as Bruis, Brus, Bruz is said to be responsible for the Adam Castle, the oldest monument in Brix.

The main square of Brix is called Place Robert Bruce.

On the first weekend of October, the commune holds the St. Denis Fair, a tradition of the Cotentin.
