Earl Warren (March 19, 1891 – July 9, 1974) was an American jurist and politician, who served as the 30th Governor of California (1943–1953) and later the 14th Chief Justice of the United States (1953–1969).

He is best known for the liberal decisions of the so-called Warren Court, which outlawed segregation in public schools and transformed many areas of American law, especially regarding the rights of the accused, ending public school-sponsored prayers, and requiring "one man–one vote" rules of apportionment of election districts. He made the Supreme Court a power center on a more even basis with Congress and the Presidency, especially through four landmark decisions: Brown v. Board of Education (1954), Gideon v. Wainwright (1963), Reynolds v. Sims (1964), and Miranda v. Arizona (1966).
