Buchanan v. Warley, 245 U.S. 60 (1917), is a case in which the Supreme Court of the United States addressed civil government-instituted racial segregation in residential areas. The Court held unanimously that a Louisville, Kentucky city ordinance prohibiting the sale of real property to blacks in white-majority neighborhoods or buildings and vice versa violated the Fourteenth Amendment's protections for freedom of contract. The ruling of the Kentucky Court of Appeals was thus reversed.
