Has anyone won the Monoco and Indy 500 in the same year?

Yes, only one driver has won both the Monaco Grand Prix and the Indianapolis 500 in the same year. That driver is Graham Hill, who achieved this remarkable feat in 1966. Hill is often referred to as "Mr. Monaco" for his success at the Monaco Grand Prix, where he won five times. His dual victory in 1966 remains a unique accomplishment in motorsport history.
