Miss America 1924, the fourth Miss America pageant, was held at the Million Dollar Pier in Atlantic City, New Jersey, on Saturday, September 6, 1924. Mary Katherine Campbell, who won the title the previous two years, placed as 1st runner-up. Pageant officials later instituted a rule allowing competitors to be crowned only once. Ruth Malcomson competing as Miss Philadelphia was named Miss America of 1924 against a field of 83 entrants, the largest number of contestants in Miss America history.

The Miss Pennsylvania competition is the pageant that selects the representative for the state of Pennsylvania in the Miss America pageant. Pennsylvania, including early years' city representatives, has won the Miss America crown on five occasions.
