Who holds the record for most Australian Open women's singles titles?

Margaret Court holds the record for the most Australian Open women’s singles titles, with 11.

Court won her titles between 1960 and 1973, taking seven consecutive championships from 1960 through 1966. She added four more during the early Open Era, when professional players were allowed to compete alongside amateurs. Her 11-title total combines the tournament’s earlier Australian Championships history with its modern Australian Open identity.

The record needs a little context because Serena Williams holds the Open Era record with seven Australian Open women’s singles titles. Court’s total is the all-time tournament record, while Serena’s figure counts only the period beginning in 1968. Court also won 24 Grand Slam singles titles overall, still the most in women’s tennis history.

Margaret Court’s Australian Open dominance was part of a remarkably broad career. She won singles, women’s doubles and mixed doubles titles at the event, and her 23 total Australian Championships/Open titles across those disciplines are also an all-time record.
