Longfellow Creek is a stream in the Delridge district of West Seattle, in Seattle, Washington. It runs about 3.38 miles (5.4 km) from Roxhill Park north to the Duwamish West Waterway at Elliott Bay. The Duwamish called the creek "Smelt" (Lushootseed: t7áWee), denoting smelt fish (Hypomesus pretiosus). The creek was a traditional fishery dating back to the 14th century.
