Bryn Mawr-Skyway (pronounced /ˌbrɪnˈmɑːr/ from Welsh for "big hill") is a census-designated place (CDP) in King County, Washington, United States.

[3] Bryn Mawr-Skyway was the only CDP in the Seattle metropolitan area to have reported a majority-minority population in the 2000 census.

As of the 2010 census, the demographic composition of the Skyway area is almost evenly distributed between White, Black or African American, and Asian community members.

Skyway lies in an "unincorporated island"[4] bordered to the north by the city of Seattle, to the west by Tukwila, and to the south and east by Renton.

[5] The neighborhood was mostly developed just after World War II as affordable housing for returning veterans.

The name "Skyway" may be derived from the area's siting on a high ridge in western Washington's hilly terrain, a name that echoes the Welsh "Bryn Mawr" (also the name used for a village and several other places), which means "big hill".

Like most inner suburbs of Seattle, Bryn Mawr-Skyway is dominated by the Democratic Party in national elections.
