On 24 April 2025, a teenage girl was killed and three students were wounded in a mass stabbing at a private secondary school, Our Lady of All Helps High School in Nantes, Loire-Atlantique, France. The suspected attacker was a 15-year-old male student and was arrested by law enforcement at the scene, after being restrained by a teacher.

Following the arrest, the suspect was put into the custody of a psychiatric hospital and examined by a psychiatrist, where he was deemed "incompatible with police custody". The court said the perpetrator was a loner who had suicidal tendencies and classmates described him as having an interest in extremism.

The stabbing occurred following previous incidents of knife violence in schools in the country and sparked discussion in regard to increasing school security, which Prime Minister François Bayrou called for following the incident.
