Sultan is a city in Snohomish County, Washington, United States. It is located approximately 23 miles (37 km) east of Everett at the confluence of the Skykomish River and the Sultan River, a minor tributary. The city had a population of 4,651 at the 2010 census.
The city was founded in 1880 at the site of a Skykomish village and initially settled during a small gold rush. Sultan was platted in 1889, just prior to the arrival of the Great Northern Railway, and was a hub for mining and the lumber industry. It was incorporated on June 28, 1905, with a population of 700. The city was home to a Civilian Conservation Corps camp during the Great Depression and undertook several civic improvements in the post-war years.
Sultan has since become a bedroom community for large employment centers in the Puget Sound region. The city has several public parks, a historic museum, and is located near outdoor recreation areas in the Cascade Mountains. It is connected to nearby cities by U.S. Route 2.
