Adlai E. Stevenson High School is a public high school located in Livonia, Michigan, a suburb west of Detroit.
Adlai E. Stevenson High School was built in 1965 to accommodate the rising population of Livonia with the increased migration of people from Detroit to the suburbs during the 1960s. It was dedicated on October 24, 1965, United Nations Day, and the 20th anniversary of that body's founding, by Vice President Hubert H. Humphrey. Stevenson was the first high school in the nation to be named for the Fifth U.S. Ambassador to the United Nations, Adlai E. Stevenson, who had died the day before the Livonia school board's decision on naming the new high school.[2] The school's first graduating class graduated in June 1968.
Stevenson is a Class A athletic school and is part of the Kensington Lakes Activities Association playing in the new East division formed in 2018.
