Monroe

Monroe is a city in Snohomish County, Washington, United States. It is located near the Cascade foothills at the confluence of the Skykomish and Snoqualmie rivers, which form the Snohomish River. The city is part of the Seattle metropolitan area and is 30 miles (48 km) northeast of Seattle. Monroe's population was 19,699 as of the 2020 census.

The town of Park Place was originally founded in 1864 at the river confluence and was among several existing settlements in the Tualco Valley. The confluence site was previously a trading post used by the indigenous Skykomish people. Park Place was renamed to Monroe in 1890 to honor U.S. President James Monroe, and was moved northeast to be near the tracks of the Great Northern Railway, which was constructed in 1892. Monroe was incorporated in 1902 and was selected as the home of a major condensed milk plant and the state reformatory.
