Serena Williams

Williams' record as the best female tennis player of all time speaks for itself. Williams has been one of the most dominant powers in women's tennis in the modern era, with 23 Grand Slam titles, one less than Margaret Court's record.

Serena Williams is the active player with the most major titles in singles, doubles, and mixed doubles, and is joint-third on the list of total major titles won. Both women have cemented their names in the sport's history books after forming one of the strongest on-court combinations with her sister Venus.

With endorsement relationships with Nike, Gatorade, Wilson, Aston Martin, IBM, and Beats by Dre, among others, the younger Williams has developed her brand. Williams is the richest female tennis player of all time, with a net worth of $200 million.
