The 61st 500 Mile International Sweepstakes was held at the Indianapolis Motor Speedway in Speedway, Indiana on Sunday, May 29, 1977. Considered one of the most historically significant editions of the Indianapolis 500, several sidebar stories complemented the unprecedented accomplishment of race winner A. J. Foyt. Foyt became the first driver to win the Indianapolis 500 four times. As of 2023, Foyt's record has been tied by Al Unser Sr., Rick Mears and Hélio Castroneves, but still stands as an Indy 500 record. Foyt's victory is also the last time the winning car was built entirely within the United States.
