Leavenworth is a city in Chelan County, Washington, United States. It is part of the Wenatchee−East Wenatchee Metropolitan Statistical Area. The population was 1,965 at the 2010 census. The entire town center is modeled on a Bavarian village as part of a civic initiative that began in the 1960s. The area is a major, four-season tourist destination with festivals nearly every month and a multitude of events year round.

The construction of the Great Northern Railway through Tumwater Canyon in 1892 brought settlers to a townsite that was named “Leavenworth”. Lafayette Lamb arrived in 1903 from Clinton, Iowa, to build the second largest sawmill in Washington state. Leavenworth was officially incorporated on September 5, 1906. A small timber community, it became a regional office of the Great Northern Railway in the early 1900s. The railroad relocated to Wenatchee in 1925, greatly affecting Leavenworth’s economy. The city’s population declined well into the 1950s as the lumber mills closed and stores relocated.
