Hamilton is a town in Skagit County, Washington, United States. The population was 299 at the 2020 census. It is included in the Mount Vernon-Anacortes, Washington Metropolitan Statistical Area.

Hamilton was first settled in 1877 by William Hamilton, and was later named for him when Hamilton was officially incorporated on March 19, 1891.^[5][6]

The town was flooded by the Skagit River in November 2021. The local post office was deemed uninhabitable due to damage from the floods and shut down despite repairs to the building. Mail and parcels bound for Hamilton are instead forwarded to the Concrete post office, located 13 miles (21 km) away, despite protests from residents.^[7]

As part of the Skagit River floodway, the town of Hamilton faces significant flooding every few years, most notably in 2003, 2006, 2017, and 2021.^[10] The frequent flooding has forced residents to adopt a routine of moving their furniture from the ground floor and evacuating to a local church until the waters recede. The Federal Emergency Management Agency (FEMA) estimates it has spent $4.6 million in the town over the last several years.^[10]

Support has been building for a plan to move the entire town to a nearby hill. The Hamilton Public Development Authority was established in 2004 to purchase the land necessary for moving the town, which was achieved with assistance from conservation group Forterra in 2018. Forterra purchased a 45-acre (18 ha) farm north of State Route 20, which it aims to develop into a green city with housing for the relocated townspeople.^[10]

The climate in this area has mild differences between highs and lows, and there is adequate rainfall year-round. According to the Köppen Climate Classification system, Hamilton has a marine west coast climate, abbreviated "Cfb" on climate maps.^[11]
