CBU-FM (105.7 MHz) is a non-commercial public radio station in Vancouver, British Columbia.

The studios and offices are in the CBC Regional Broadcast Centre at 700 Hamilton Street in Downtown Vancouver.

Broadcast relay stations carry CBU-FM programming around British Columbia, as well as Dawson City, Whitehorse and Yellowknife.

At first it was an FM simulcast of Vancouver's original CBC AM station, which had the call sign CBR.

However, Saturday Afternoon at the Opera and In Concert, both hosted by Bill Richardson, currently originate from Vancouver for the entire network.
