Stop Suicide is a non-profit organization committed to preventing youth suicide in the Romandy region. It was founded in 2000, following a silent march organized by students affected by the suicide of one of their peers. The association's mission is to address and encourage open conversations about suicide, raise awareness, inform, and enhance prevention efforts.

Each year, Stop Suicide runs a prevention campaign, conducts workshops for young people, participates in training programs at higher education institutions and universities, and provides guidance to education and media professionals concerned with the topic of suicide.
