Le Puy (French pronunciation: [lə pɥi]; Gascon: Lo Puèi) is a commune in the Gironde department in Nouvelle-Aquitaine in southwestern France.

Le Puy lies 65 km (40 mi) from Bordeaux on the intersection of the D15 and the D16 and 1 km (0.62 mi) from Monségur across the river Dropt.

The economy is agricultural, with wheat, sunflowers and soya being grown in recent years to complement the more traditional plums and tobacco.

The locality produces the famous Entre deux mers wine.

Mill reservoirs can provide good fishing for roach, carp and pike.

The region is well known for its cèpes (boletus mushroom).

The town lies in the Dropt basin which covers nearly 1,500 km (580 sq mi) in Guyenne, from Quercy to the Bordelais. The river is an affluent of the right bank of the Gironde.

The alluvial plain of the Dropt is characterized by boulbène (a soil composed of clay and sand) terraces, rising to foothills of molasse (chalky sandstone sedimentary deposits) with a few hillocks or the edges of chalky plateaus.

The town was a halting place on the pilgrimage to Santiago de Compostela.

The Sisters of St. Joseph were founded in Le Puy in 1650 by Jesuit Priest Jean Pierre Medaille.

The town lost 10 soldiers during World War I.
