# List of female Major League Baseball principal owners

Since the beginning of Major League Baseball, women have rarely held high executive positions in team franchises. On occasion, however, women have ended as majority owners of Major League franchises. Most often, they end up inheriting their team from their families. As a result, there have been fourteen women who have held the controlling stakes of a franchise in the league's history.
The first female owner in MLB history was Helene Hathaway Britton, the daughter of Frank Robison and the niece of Stanley Robison. She inherited the St. Louis Cardinals from her uncle upon his death and, despite pressure to sell from fellow male owners, chose to retain ownership and control of the team and took an active part in running it until financial issues forced her to sell. Grace Comiskey inherited the team from her husband J. Louis Comiskey and became team President, the first woman in the American League to hold a high executive role. Her daughter Dorothy Comiskey Rigney inherited the team from her.
Two women have independently owned majority stakes of an MLB franchise without inheriting it. Joan Whitney Payson, previously a minority owner of the New York Giants, was the first owner of the New York Mets and played a big role in bringing the National League back to New York City after the Giants and Brooklyn Dodgers moved to the West Coast. She was the first woman to own a team without having inherited it. Marge Schott was the first woman to purchase a Major League franchise when she bought the Cincinnati Reds in 1984.
Additionally, a number of women have inherited the team upon the death of a family member but delegated the business of running to someone else. For instance, Edith Dunn, the wife of Cleveland Indians owner Jim Dunn, was the first woman in the American League and second overall to own a franchise but did not take part in its day-to-day operations, instead letting general manager Ernest Barnard run the team until she sold it upon remarrying in 1927. Unusually, baseball executive Mae Nugent inherited the majority shares of the Philadelphia Phillies from owners William and Laura Baker upon their deaths but her husband Gerald Nugent ran the day-to-day operations.
