Braddock Heights is an unincorporated community and census-designated place (CDP) in Frederick County, Maryland, United States. The population was 2,608 at the 2010 census.
Braddock Pass is near the locations at which Interstate 70 and the National Pike (U.S. Route 40) cross Catoctin Mountain. Braddock Heights was founded in 1896 by George William Smith as a summer resort community that eventually included several hotels, a community pool, a wooden-floor skating rink, an amusement park, scenic overlooks, nature trails, and until 1980, a small ski resort. Braddock Heights has been host to many national political figures, including Oliver Wendell Holmes, Sr., Edwin Warfield, President Franklin D. Roosevelt, Earl Warren, Ethel Kennedy, and (then) Senator Richard Nixon. Braddock Heights was one of the first modern planned communities in the United States, and custom housing development has continued since 1901. Braddock Heights is now known for its eclectic houses (no two are alike) and its scenic views of Frederick and the Monocacy and Middletown valleys. Following the end of World War II and the decline of the amusement park, Braddock Heights' demographic changed from commercial summer boarding houses to that of an unincorporated community with permanent residents.
