Chevy Chase —formally, the Town of Chevy Chase—is an incorporated town in Montgomery County, Maryland, United States. The population was 2,904 at the 2020 census.

Chevy Chase is the colloquial name of an area that includes a town, several incorporated villages, and an unincorporated census-designated place in southern Montgomery County, Maryland; and one adjoining neighborhood in northwest Washington, D.C. Most of these derive from a late-19th-century effort to create a new suburb that its developer dubbed Chevy Chase after a colonial land patent.
