Beaussac (French pronunciation: [bosak]; Limousin: Baussat) is a former commune in the Dordogne department in Nouvelle-Aquitaine region in southwestern France.

[2] The community is located in the Périgord Limousin Regional Nature Park.

On Cassini's early map of France between 1756 and 1789, the village is identified as the Beaussat.

The stream of Beaussac (ruisseau de Beaussac), a tributary of the Lizonne, forms the commune's southeastern border and part of the commune's southwestern border, separating it from Puyrenier and Rudeau-Ladosse.

The town is located 34.1 kilometres (21.2 mi) southeast of Angoulême, the largest nearby city.
