Saint-Léonard-de-Noblat (French pronunciation: [sɛ̃leɔnaʁ də nɔbla]; Occitan: Sent Liunard, [sɛ̃ ʎo'nar], alternatively Sent Liunard de Noblac), often simply referred to as Saint-Léonard, is a commune in the Haute-Vienne department in the Nouvelle-Aquitaine region in west-central France, on a hill above the river Vienne.

Saint-Léonard-de-Noblat is one of the UNESCO World Heritage Sites connected with the routes to Santiago de Compostela.

Dating partly from the 11th century, the church is a listed historic monument.

The place also attracts visitors as an overnight stop on the Tour de France.

The town is known for its native son, the scientist Joseph Louis Gay-Lussac (1778–1850); there is a small museum in his honor.
