Robyn Choi is a woman of Korean ethnicity born in Sydney, Australia and raised on the Gold Coast. She attended the University of Colorado starting in 2016.

In Fall of 2018, Choi attended the LPGA's Q-Series, where she managed to finish tied for 45th. This earned her one of the final category 14 tour cards for the 2019 season. She decided to leave college and turn join the LPGA.

In 2019, Choi played 13 LPGA events and 9 Symetra Tour events. For the most part she missed the cut on the LPGA; her best finish was a t-36th at the team event the Dow Great Lakes Bay Invitational. She lost her tour card for 2020.

In early 2020, she returned to Australia, where she played 2 events on sponsor's invites. They ended up being her two best LPGA finishes ever: a t-34th at the Handa Women's Australian Open, and a t-6th at the Vic Open. She even had a decent chance to win at the Vic, but came up just short.

Choi spent the next several years on the Symetra/Epson Tour but was not able to regain her LPGA membership. Finally, in 2023, she went to Q-Series and had a fantastic week, sitting in or near the lead all week and eventually winning Q-Series outright. She earned a full card for the 2024 season.
