CKCU-FM is a Canadian campus-based community radio station, broadcasting at 93.1 FM in Ottawa and www.ckcufm.com, and offering live and archived on-demand audio streams from its website.

CKCU actively supports, sponsors and promotes local independent musicians, venues, concerts and festivals.

Often dubbed the mighty 93 by devotees, CKCU has a freeform format that allows the hosts to pick all the music played, and has many community programs.

Each March break and several times during the summer, CKCU runs a unique Radio Camp for kids ages 10–14.
