Fourth Ward is one of the historic six wards of Houston, Texas, United States. The Fourth Ward is located inside the 610 Loop directly west of and adjacent to Downtown Houston. The Fourth Ward is the site of Freedmen's Town, which was a post-U.S. Civil War community of African-Americans.

Downtown is the largest central business district in the city of Houston and the largest in the state of Texas, located near the geographic center of the metropolitan area at the confluence of Interstate 10, Interstate 45, and Interstate 69. The 1.84-square-mile (4.8 km2) district, enclosed by the aforementioned highways, contains the original townsite of Houston at the confluence of Buffalo Bayou and White Oak Bayou, a point known as Allen's Landing. Downtown has been the city's preeminent commercial district since its founding in 1836.
