  Ranked No. 361, on her Grand Slam tournament debut at the 2025 French Open, Boisson reached a semifinal for the first time, recording her first major wins, as a wildcard, defeating 24th seed Elise Mertens, Anhelina Kalinina, fellow wildcard Elsa Jacquemot, world No. 3, Jessica Pegula, and world No. 6 seed and former semifinalist, Mirra Andreeva. Boisson was the first woman to make the quarterfinals in her major main-draw debut since Carla Suárez Navarro made the last eight in 2008 as a qualifier. Boisson became the lowest-ranked quarterfinalist and semifinalist at Roland Garros in the last 40 years, and the lowest quarterfinalist at any Grand Slam event since 2017 (No. 418 Kanepi at the US Open). She became the first woman in 35 years to reach the semifinals at their first major since Jennifer Capriati in 1990, and the first Frenchwoman since Marion Bartoli in 2011, into the Roland Garros semifinals. Her run was ended by eventual champion and second seed Coco Gauff. As a result, she reached world No. 65, moving nearly 300 positions up and entering the top 100 in the singles rankings with the biggest leap of the 21st century. She became the French No. 1 player on 9 June 2025.
