Leona Maguire (born 30 November 1994) is an Irish professional golfer. She held the record for the most weeks at the top of the World Amateur Golf Ranking, and in 2022 became the first — and, to date, only — Irish woman to win on the LPGA Tour. In 2024 she became the first Irish woman to win on the Ladies European Tour.
With a score of 61 in the final round of the 2021 Evian Championship, Maguire holds the record for the lowest-ever score in the final round of any major championship (men or women) and the joint lowest round in any round of a major. During the 2021 Solheim Cup, she broke the all-time rookie points record in either the Solheim Cup or the Ryder Cup with a total of 4.5.
