The march follows a torrent of assault and harassment allegations against public figures, set off by revelations about the movie mogul Harvey Weinstein.
The marchers started on Hollywood Boulevard and walked along the "Walk of Fame" to CNN's headquarters.
They were predominantly women but many men attended.
Tara McNamarra, 21, of Los Angeles, told Reuters news agency that the march felt cleansing after years of not being taken seriously about abuse.
