Galvez is an unincorporated community in Ascension Parish, Louisiana, United States, ten miles (16 km) southeast of Baton Rouge.

In 1778, Loyalists from Canewood, an English settlement on the eastern banks of the Amite river petitioned Count Bernardo de Gálvez, the colonial Governor of Louisiana and viceroy of New Spain (future Mexico) for permission to settle on the Spanish side of this river to escape torment from supporters of the American Revolution.

Gálvez sent settlers from the Canary Islands, known as Isleños, to Galveztown in 1779, hoping to establish a military stronghold against the British in West Florida, who controlled nearby Baton Rouge at the time.

Although the Spanish fort, streets, and homes remained as ruins in Galveztown for well over a century, no effort was made to preserve the site.

The modern location of Galvez is to the southwest of the original settlement, at an area later homesteaded by farmers and ranchers during the latter half of the 19th Century.
