High Quality Content by WIKIPEDIA articles! Oak Cliff is a community in Dallas, Texas, United States that was formerly a separate town located in Dallas County; Dallas annexed Oak Cliff in 1903. It has since retained a distinct neighborhood identity as "Dallas' older, established neighborhood". Oak Cliff has turn-of-the-century and mid-20th century housing, many parks, and proximity to the central business district of downtown Dallas. The boundaries of Oak Cliff are roughly Interstate 30 and the Trinity River on the north, Interstate 35E on the east, Camp Wisdom Road on the south, and Cockrell Hill Road on the west. In practice nearly every neighborhood south of the Trinity River (excluding west Dallas) is called Oak Cliff,[citation needed] though much of it was never part of the original town. For example, the South Oak Cliff neighborhood (one of the primary African-American neighborhoods in Dallas),[citation needed] which generally includes neighborhoods south of Illinois Avenue, was never part of the original town of Oak Cliff. Neighborhoods east of I-35 are normally considered part of Oak Cliff as well, in addition to the undeveloped parts of the Mountain Creek area.
