Arlington is a city in northern Snohomish County, Washington, United States, part of the Seattle metropolitan area. The city lies on the Stillaguamish River in the western foothills of the Cascade Range, adjacent to the city of Marysville. It is approximately 10 miles (16 km) north of Everett, the county seat, and 40 miles (64 km) north of Seattle, the state's largest city. As of the 2020 U.S. census, Arlington had a population of 19,868; its estimated population is 20,075 as of 2021. The city lies in the traditional territory of the Stillaguamish people, an indigenous Coast Salish group. Arlington was established in the 1880s by settlers and the area was platted as two towns, Arlington and Haller City. Haller City was absorbed by the larger Arlington, which was incorporated as a city in 1903. During the Great Depression of the 1930s, the Arlington area was the site of major projects undertaken for employment under the direction of federal relief agencies, including construction of a municipal airport that would serve as a naval air station during World War II. Arlington began suburbanizing in the 1980s, growing by more than 450 percent by 2000 and annexing the unincorporated area of Smokey Point to the southwest. The economy of the Arlington area historically relied on timber and agriculture. In the early 21st century, it has transitioned to a service economy, with some aviation industry jobs near the municipal airport. The city is governed by a mayor–council government, electing a mayor and seven city councilmembers. The municipal government maintains the city's parks system and water and wastewater utilities. Other services, including public utilities, public transportation, and schools, are contracted to regional or county-level agencies and companies.

The Trafton Elementary School in Arlington, Washington, USA was founded in 1888, rebuilt after a fire in 1912, and is listed on the Washington State Heritage Register and the National Register of Historic Places. In February 2010, the Arlington School District was considering closing the school after the current school year. Then in June they indeed voted to do so.The two-story building, described in 2010 by the Everett Herald as "the oldest continuously operating small school in Washington", still retains its old school bell on the roof. It is the focal point of the Trafton community northeast of Arlington proper, and is the site of the annual Trafton Fair every September. As of 2010, the K-5 school has 135 students, from about 70 families.Faced with a $2.4 million budget crunch from the late-2000s recession, Arlington decided to close the school. According to the Everett Herald, Arlington's Eagle Creek Elementary School several miles away was "about 200 students below its capacity and could easily take in the staff and students from Trafton." Trafton needed about $850,000 in repairs and improvements, which would have had to be funded by a bond issue if the school was to remain open; conversely, rolling Trafton into Eagle Creek was projected to save an estimated $300,000 a year.It was later renovated into a 5,392 sq. ft private residence and placed on the market in 2023 for $1.5 million.
