Mukilteo was incorporated as a city in 1947 and saw new suburban development, which accelerated after the opening of the nearby Boeing Everett Factory in the late 1960s. Mukilteo was used during World War II as an auxiliary fueling facility, due to its proximity to the newly built Snohomish County Airport (now Paine Field). The area remained a trading post for loggers and was home to other industries, but was overshadowed by Everett and grew slowly. A new town was founded at Mukilteo and served as the provisional county seat of Snohomish County in early 1861. The Treaty of Point Elliott was signed in Mukilteo in 1855, opening the region to American settlement. The current site of downtown Mukilteo (also named Old Town) has been inhabited by the Snohomish people for at least 1,000 years before present. The city had a population of 20,254 at the 2010 census and an estimated 2019 population of 21,441.
It is located on Puget Sound between Edmonds and Everett, approximately 25 miles (40 km) north of Seattle. Mukilteo ( / ˌ m ʌ k əl ˈ t iː oʊ/ MUK-əl- TEE-oh Lushootseed: bək̓ʷəɬtiwʔ ) is a city in Snohomish County, Washington, United States.
