The area of Galena Park began as the settlement of Clinton in 1835. The settlement originally served as a farming and ranching community but in the 1880s transformed into a railroad Center along the new Port of Houston. With the coming of the petrochemical industry in the Early 1900s, Clinton again transformed into a refinery center. Galena Park's original name survives today as the name of a major street in the city, Clinton Drive. Because of the 1935 incorporation, Houston did not incorporate Galena Park's territory into its city limits, while Houston annexed surrounding areas that were unincorporated. By the late 1930s Houston was growing as a port, so Galena Park expanded. Since the 1940s area residents considered the city to be a part of Greater Houston. Galena Park is a city in Harris County, Texas within the HoustonSugar LandBaytown metropolitan area. The population was 10,887 at the 2010 census.
