The Infosys Hall of Fame Open is an international tennis tournament that has been held every year in July since 1976 at the International Tennis Hall of Fame in Newport, Rhode Island, the original location of the U.S. National Championships.

The event, which was part of the Grand Prix tennis circuit from 1976 to 1989, typically features a 32-player singles draw and a 16-team doubles tournament.

The tournament is held on outdoor grass courts, and is the only grass court tournament played outside Europe.

Up until 2011, when John Isner won the tournament,[1] the top seed had never triumphed at Newport, a trait that has led to the moniker "the Casino Curse", due to the location of the Hall of Fame at the Newport Casino.

The International Tennis Hall of Fame induction ceremony, formerly held during the tournament, was shifted to August.
