The Galena Park Independent School District was established in 1929 with one common school in the city of Clinton, TX. When the City of Clinton was renamed Galena Park for the Galena-Signal Oil Company in 1930, so was the school district.
Galena Park ISD is a K-12 public school district serving more than 22,000 students on 24 campuses in East Harris County.
Today, the district includes the Cities of Galena Park & Jacinto City, a small portion of the City of Houston and several unincorporated communities in East Harris County such as Home Owned Estates, Hidden Forest, Cloverleaf, Woodforest, Pine Trails and New Forest.
