Known for her agility and sharp reflexes, the two-time UEFA Women’s Champions League winner joins the Eagles from National Women’s Soccer League club Denver Summit.
Peyraud-Magnin has established herself as one of the finest goalkeepers in the game since her OL Lyonnes debut in the 2012/13 season.
She spent seven years in France - playing for Issy (now Paris SO Cœur), Saint-Étienne, and Marseille between her two stints at Les Lyonnaises.
She was a part of the Lyonnes squad that lifted a record fifth Champions League during the 2017/18 season, before making a move to Arsenal in the summer of 2018.
Peyraud-Magnin represented the Gunners for two seasons and then swapped England for Spain in 2020, where she joined Atlético Madrid.
A productive spell in the Spanish capital earned Peyraud-Magnin a move to Juventus in 2021, where she won five trophies across five seasons.
She joins Palace after a brief spell in the United States, where she represented NWSL debutant Denver Summit.
The 34-year-old has earned over 70 caps for France and has been selected for four major tournaments to date: the 2019 and 2023 FIFA Women’s World Cups, UEFA Women’s Euro 2022, and the 2024 Olympics.
Manager Jo Potter said: “Pauline's career and experience speaks for itself - she is a great addition for us this season.”
After signing, Peyraud-Magnin said: “I’m really excited to get started.
“It's a really good opportunity for me to play again in England, in the best league in the world.”
