Clara Tauson won her first WTA singles tennis title as a qualifier, defeating
Viktorija Golubic in the final of the 2021 Lyon Open, 6–4, 6–1. Tauson did not drop a set throughout the entire tournament, including qualifying rounds, and dropped just 35 games across seven matches. Tauson became the second Danish player in history, after
Caroline Wozniacki, to win a WTA Tour singles title. The final match was the first WTA singles final to be contested between two qualifiers since the
2017 Japan Women's Open.
Sofia Kenin was the defending champion,[1] but chose not to participate after undergoing surgery for appendicitis.[2]
