Kelsey Creek is a creek in Bellevue, Washington on Seattle's Eastside. Originating in the wetlands in the Lake Hills greenbelt between Phantom Lake and Larsen Lake, it flows north and west through the Crossroads neighborhood and then south to Kelsey Creek Park where it turns west and becomes the Mercer Slough just west of Interstate 405. The centerpiece of the largest wetland adjacent to Lake Washington at 367 acres (149 ha), the slough empties into the East Channel of Lake Washington at Interstate 90.
