Baytown is a city within Harris County and partially in Chambers County in the Gulf Coast region of the U.S. state of Texas. Located within the Houston–The Woodlands–Sugar Land metropolitan area, it lies on the northern side of the Galveston Bay complex near the outlets of the San Jacinto River and Buffalo Bayou. It is the sixth-largest city within this metropolitan area. Major highways serving the city include State Highway 146 and Interstate 10. As of 2010, Baytown had a population of 71,802, and it had an estimated population of 77,192 in 2019.
White settlers first arrived in the now-Baytown area in 1822. One of its earliest settlers was Nathaniel Lynch, who set up a ferry crossing at the junction of the San Jacinto River and Buffalo Bayou. The still-operating ferry service is known as the Lynchburg Ferry. Other early settlers of Baytown included William Scott, one of Stephen F. Austin's Old Three Hundred, and Ashbel Smith, who owned a plantation in the area.
The city now known as Baytown was originally three separate towns. The first of these was Goose Creek, named for the bayou of the same name where Canada geese wintered and whose name is still reflected in the area's Goose Creek school district, whose establishment dates back to before 1850.
