Miss America 1941, the 15th Miss America pageant, was held at the Boardwalk Hall in Atlantic City, New Jersey on September 6, 1941. Shortly after the crowning of Miss California, Rosemary LaPlanche, who had been first runner-up in 1940, the pageant committee adopted this rule: "No contestant can compete in Atlantic City for the title of Miss America more than once", thus eliminating future state winners with more than one attempt at the national title. LaPlanche became a film actress, as did her sister, Louise LaPlanche.
