Stephen Fuller Austin (November 3, 1793 – December 27, 1836) was an American-born empresario. Known as the "Father of Texas" and the founder of Anglo Texas, he led the second and, ultimately, the successful colonization of the region by bringing 300 families and their slaves from the United States to the tejanos region in 1825.

Born in Virginia and raised in southeastern Missouri, Austin served in the Missouri territorial legislature before moving to Arkansas Territory and later Louisiana. His father, Moses Austin, received an empresario grant from Spain to settle Texas. After Moses Austin's death in 1821, Stephen Austin won recognition of the empresario grant from the newly independent state of Mexico. Austin convinced numerous American settlers to move to Texas, and by 1825 Austin had brought the first 300 American families into the territory. Throughout the 1820s, Austin sought to maintain good relations with the Mexican government, and he helped suppress the Fredonian Rebellion. He also helped ensure the introduction of slavery into Texas despite the attempts of the Mexican government to ban the institution. He led the initial actions against the Karankawa people in this area.

As Texas settlers became increasingly dissatisfied with the Mexican government, Austin advocated conciliation, but the dissent against Mexico escalated into the Texas Revolution. Austin led Texas forces at the successful Siege of Béxar before serving as a commissioner to the United States. Austin ran in the 1836 Texas presidential election but was defeated by Sam Houston, who entered the race just two weeks before the election. Houston appointed Austin as Secretary of State for the new republic, and Austin held that position until his death in December 1836.

Numerous places and institutions are named in his honor, including the capital of Texas, Austin County, Austin Bayou, Stephen F. Austin State University, Austin College, and numerous public schools.
