United under the slogan “Don’t tell me how to dress, tell them not to rape”, the demonstrators will begin their march at Quai des Forces Motrices at 2pm.
“Rape is never provoked,” the SlutWalk Switzerland group said in a statement.
“No victim of sexual abuse wanted to be abused or is responsible for their rape.”
The SlutWalk movement began in Toronto, Canada, in 2011 in reaction to comments by a police officer who said “women should avoid dressing like sluts” to stay safe.
It has since spread to cities around the world.
SlutWalk Switzerland said it wanted the Geneva march to help combat the country’s “weak” legislation, with rape defined as “a sexual act committed against a person of the female sex”.
“A man, then, cannot be raped; oral and anal penetration are not considered rape,” SlutWalk Switzerland said.
The group also said more resources needed to be set aside for proper police training.
After the walk, victims of sexual violence will speak about their experiences at Place des Volontaires.
Burlesque performers and musicians will then entertain the crowd at the square.
