Elgin ( /ˈɛlɡɨn/) is a city in Bastrop and Travis Counties in the U.S. state of Texas. The population was 5,700 at the 2000 census. By 2005, the population grew to an estimated 8,689. Elgin is also known as The Sausage Capital of Texas and the Brick Capital of the Southwest due to the presence of three operating brickyards in the mid-twentieth century (two of which are open to this date).

W. Du Bois, an Elginite, who took a competency there and doubled it, now owning forty-two square miles of well stocked land, and the 300,000 acre pasture of a Mr. Gibbs, who is interested in the venture.
