Saint-Savin (French pronunciation: [sɛ̃ savɛ̃]), also referred to as Saint-Savin-sur-Gartempe (pronounced [sɛ̃ savɛ̃ syʁ ɡaʁtɑ̃p], literally Saint-Savin on Gartempe), is a commune in the Vienne department in the Nouvelle-Aquitaine region in western France.

It is located on the banks of the Gartempe.

The Romanesque Abbey Church, begun in the mid 11th century, contains many beautiful 11th- and 12th-century murals which are still in a remarkable state of preservation.

It has been a UNESCO World Heritage Site since 1983.
