David George MacDonald was an American racing driver noted for his successes driving Corvettes and Shelby Cobras in the early 1960s. He was killed in the 1964 Indianapolis 500, along with fellow driver Eddie Sachs.

The 48th International 500-Mile Sweepstakes was held at the Indianapolis Motor Speedway in Speedway, Indiana on Saturday, May 30, 1964. The race was won by A. J. Foyt, but is primarily remembered for a fiery seven-car accident which resulted in the deaths of racers Eddie Sachs and Dave MacDonald. It is also the last race won by a front-engined "roadster", as all subsequent races have been won by rear-engined, formula-style cars. It was Foyt's second of four Indy 500 victories.
