This is a list of the main career statistics of Australian former tennis player Margaret Court. She won 64 Grand Slam events (24 singles, 19 doubles, 21 mixed doubles), which is a record for a male or female player. Her 24 Grand Slam singles titles and 21 in mixed doubles are also all-time records for both sexes. She achieved a career Grand Slam in singles, doubles, and mixed doubles. She is one of three women to have achieved the Grand Slam in singles (alongside Steffi Graf and Maureen Connolly), and is the only woman to have achieved the mixed doubles Grand Slam, which she did twice.

Her career singles win-loss record was 1,177-106, for a winning percentage of 91.74 percent on all surfaces (hard, clay, grass, carpet), is also an all-time record.
