Rainier Beach is a set of neighborhoods in Seattle, Washington that are mostly residential. Also called Atlantic City, Rainier Beach can include Dunlap, Pritchard Island, and Rainier View neighborhoods.
The neighborhood is located in the far southeastern corner of the city along Lake Washington. Its primary arterials are Rainier and Renton Avenues South (northwest- and southeast-bound).
Neighborhood boundaries are informal and sometimes overlapping in Seattle; formal designations have not existed since 1910. Rainier Beach blends with the Rainier Valley neighborhood of Dunlap (also called Othello) on the north. On the east is Lake Washington, and the South Beacon Hill neighborhood lies to the west. South of Rainier Beach is Rainier View, bounded by South Bangor Street on the north and the city boundary on its south, east, and west. The Lakeridge and Skyway neighborhoods of unincorporated King County lie to the southeast and southwest, respectively, of Rainier View. The city of Tukwila abuts Rainier View on the west.
