Plessy v. Ferguson (1896), was a landmark decision of the U.S. Supreme Court that upheld the constitutionality of racial segregation laws for public facilities as long as the segregated facilities were equal in quality, a doctrine that came to be known as "separate but equal".

The underlying case originated in 1892 when Homer Plessy, resident of New Orleans, deliberately violated Louisiana's Separate Car Act of 1890, which required "equal, but separate" train car accommodations for white and non-white passengers.
