San Felipe (/ˌsæn fɪˈliːp/ SAN fi-LEEP), also known as San Felipe de Austin, is a town in Austin County, Texas, United States. The town was the social, economic, and political center of the early Stephen F. Austin colony. The population was 691 at the 2020 census.

In 1823, John McFarland operated a ferry on the Brazos River near this location. In the fall of the same year, the site was chosen by Stephen F. Austin, with the help of Felipe Enrique Neri, Baron de Bastrop, to be the main site in Texas for American colonization. Founded in 1824 as San Felipe de Austin, the town served as the capital of Stephen F. Austin's first colony and the founding site of the Texas Rangers.

By 1828, San Felipe had been surveyed, with Calle Commercio laid out as the main commercial street. Austin and his secretary, Samuel May Williams, both resided in log cabins on the square. There were about 30 buildings, and at least one of these was a wood-framed structure. Also on the square was the tavern of Jonathan Peyton. Starting in 1830, James (Jack) Cummins operated a nearby lumber mill and grist mill, and about the same time, settlers raised livestock in the area.

By 1835, the town's population had increased to around 600.

It was home to the first post office and one of the earliest newspapers and land offices in Texas. San Felipe was second only to San Antonio as a commercial center of Texas.

The Texas conventions of 1832 and 1833 and the Consultation of November 3, 1835, were held here. San Felipe acted as the capital for the provisional government of Texas until the Convention of 1836. The town was burned in 1836 to prevent the Mexican army from capturing it, and rebuilt a few years later, but never regained its popularity. The oldest post office in Texas is located here (ZIP code 77473).

Local residents dedicated the original townsite as a commemorative site in 1928. In 1940, the town of San Felipe donated most of the original townsite property to the state, which is now the San Felipe de Austin State Historic Site.
