Kylie Masse

Kylie Jacqueline Masse (born January 18, 1996) is a Canadian competitive swimmer. A noted backstroke specialist, she is a five-time Olympic medallist, three-time World Aquatics champion, three-time Commonwealth Games gold medallist, and the 2018 Pan Pacific champion in the 100 metre backstroke.

After early success swimming at the university level, Masse had a breakout appearance at the 2016 Summer Olympics, winning a bronze medal in the 100 metre backstroke. Her victory in the same event at the 2017 World Aquatics Championships saw her become the first Canadian woman to win a swimming world title, in the process breaking an eight-year-old world record. She subsequently became the first Canadian woman to defend her world title at the 2019 World Aquatics Championships. She would win a third World Aquatics title, this time in the 50 metre event, in 2022. After collecting three medals at the 2020 Summer Olympics, her bronze medal in the 200 metre backstroke at the 2024 Summer Olympics made her the second Canadian swimmer to medal in three consecutive Olympic Games. Masse currently holds the Canadian record for medals at World Aquatics' short course and long course world championships, with a total of twenty-one.
