The 500 Festival Open Invitation was a professional golf tournament on the PGA Tour, played during the 1960s in Indianapolis, Indiana.

In 1961 Doug Ford won on the second hole of a sudden-death playoff over Arnold Palmer.

The one-day turnaround required grounds crews to quickly clean up the nine holes inside the track, used on race day for parking by fans.

Considerable attention was given to the fact that several top names on the PGA Tour decided to skip the event.

Gary Player sank a birdie putt on the final hole to clinch the victory.
