Fanlac (French pronunciation: [fɑ̃lak]) is a commune in the Dordogne department in Nouvelle-Aquitaine in southwestern France.

The maximum elevation with 267 or 269 meters, is located in the northeast at the place called Les Quatre Bornes, in the boundaries of three other communes, Bars, Auriac-du-Périgord and Montignac.

Within a few kilometres, access to the municipality can be made from the departmental roads D31 (to the north-west), D45 (to the South), D67 (to the north) or D706 (to the southeast).

This route starts from the la Forge d'Ans where cannons were made to arrive at the pier at Moustier.

The Château du Sablou was an internment camp for the "undesirable French Communists", Alsatian autonomists and Gypsies during 1940.

Gabriel and Jeanne Aubarbier lived in Lespicerie, an old farmhouse in the forest, west of the village, going towards le Bos de Plazac.

The Lespicerie farm was discovered and immediately bombarded, but the resistance fighters had time to escape.

Finding nothing, the German soldiers left in the morning but returned in the afternoon and were directed to the Aubarbier couple, who were killed.

Two plaques honour the memory of the Aubarbier couple: one on the western facade of the church, the other on the wall of their burnt house in the village of Fanlac.

Shooting a film at Fanlac at the time proved to be an entertainment for its inhabitants, and the Fanlacois were numerous among the extras.

In the context of the 2014 reform, defined by the decree of 21 February 2014, the canton disappeared in the departmental elections of March 2015.
