Juan Nepomuceno Seguín was a Spanish-Tejano political and military figure of the Texas Revolution who helped to establish the independence of Texas. Numerous places and institutions are named in his honor, including the county seat of Seguin in Guadalupe County, the Juan N. Seguin Memorial Interchange in Houston, Juan Seguin Monument in Seguin, World War II Liberty Ship SS Juan N. Seguin, Seguin High School in Arlington.

Tejanos are descendants of Texas Creoles and Mestizos who settled in Texas before its admission as an American state. The term is also sometimes applied to Texans of Mexican descent.
