The South End is a group of neighborhoods in southeastern Seattle, Washington. The definition is a bit fluid, but has traditionally included the area south of the Central District, and east of Interstate 5: Rainier Valley, Columbia City, Rainier Beach, Seward Park, Mount Baker, and Beacon Hill. Sometimes its definition is extended to Skyway and Bryn Mawr in unincorporated King County, though these are not technically in the city. Other definitions have included northern parts of Renton and Tukwila, though most Seattleites, especially those from the South End, would consider this usage incorrect. Often the term "South End" is used colloquially to include neighboring portions of South King County, by people living in those areas, due to that area's location in reference to Seattle proper.
