Highline High School is a high school in Burien,  Washington, located about 3.5 highway miles from Seattle-Tacoma International Airport.  Highline High School, the flagship high school of the Highline School District. opened its doors in 1924 and served the cities of Burien, Des Moines, and an area south of Seattle now known as White Center. Today those cities all have their own area high schools, but at the time Highline was the only high school in the area.

The name Highline, for which the school was named, derives from the original name for Des Moines Memorial Drive, which was called the "High Line Road" for its location along the ridge between Puget Sound and the Miller Creek Valley. Today the name represents the geographic area for Burien, Sea-Tac, Des Moines and White Center. As one of the oldest high schools in Washington State, Highline High School has a long tradition of sports, academic, and community service excellence.

Adjacent to the school is the Highline Performing Arts Center, which is used by the local community organizations, schools, and dance competition companies.
