Chelan (/ʃəˈlæn/ shə-LAN) is a city in Chelan County, Washington, United States. The population was 3,890 at the 2010 census. The population was 4,222 at 2018 Estimate from Office of Financial Management. It lies on the southeast tip of Lake Chelan, where the lake flows into the Chelan River.

Chelan is part of the Wenatchee−East Wenatchee Metropolitan Statistical Area. The Chelan area was home to Salish speaking Native Americans known as the Chelan tribe prior to white settlement in the late 1800s. But before the settlers arrived, a new beast, the horse, came and with it just as quickly were smallpox, measles and other deadly infectious diseases. These diseases wiped out an estimated 90% of the Indians before David Thompson, the very first explorer in the area, arrived on the Columbia in 1811.
