Mathilde Froustey (born June 8, 1985, in Bordeaux, France) is a French ballet dancer.

She is a principal dancer at San Francisco Ballet. Mathilde Froustey was a "Sujet" soloist of the Paris Opera Ballet until 2013.

Mathilde Froustey started dancing in 1994, at the age of nine, in Dax in the south of France, as ballet training helped her back problems. Later, in 1998, she trained at the Marseille National School of Ballet. Colette Armand, her ballet teacher in Marseille, recommended she audition for the prestigious Paris Opera Ballet School.

Mathilde Froustey started at Paris Opera Ballet School in 1999 and joined Paris Opera Ballet in 2002. She was promoted to the rank of "Coryphée" in 2003.

In 2004, she won the gold medal at the Varna International Ballet Competition with Josua Hoffalt. In 2005, Froustey was promoted to "Sujet", soloist.

Froustey was one of the founding members of 3e étage, an independent group of Paris Opera Ballet dancers directed by Samuel Murez.

She toured in Japan with Manuel Legris as a member of his group Manuel Legris & Friends. Legris was at the time principal dancer ("danseur étoile") of the Paris Opera Ballet.

Although Froustey appeared on stage in leading roles with the Paris Opera Ballet as of 2006, particularly as Kitri in Don Quixote, she was not promoted to "Première Danseuse", first soloist, with this company. Artistic director, Brigitte Lefèvre, could not explain why the jury consistently didn’t vote for her. Some ventured that her style was too extroverted and virtuosic for Paris, where restraint and purity are valued.
