Pasadena, city in southeastern Texas, in Harris County. The city is located in the southeast Houston metropolitan area, immediately south of the Houston Ship Channel and west of Galveston Bay. It is an oil-field service center and contains numerous refineries and other industries producing paper, petrochemicals, and construction materials.
The Lyndon B. Johnson Space Center, operated by the National Aeronautics and Space Administration (NASA), is an important local employer. The city is the seat of the University of Houston-Clear Lake (1971), Texas Chiropractic College (1908), and a junior college. Pasadena is near the state park enclosing the site of the Battle of San Jacinto (1836), in which Texans defeated Mexico in a decisive encounter in the Texas Revolution. The 20th-century warship USS Texas, now containing a museum, is moored in the park. The Armand Bayou and Nature Center, a large nature preserve, is also within the city.
