CBC Radio is the English language radio division of the Canadian Broadcasting Corporation. CBC Radio has three branches:

• CBC Radio One - news and information (until 1997 simply "CBC Radio")
• CBC Radio Two - music, arts and culture
• CBC Radio Three - youth oriented programming on Internet radio and Sirius Satellite Radio (although some content from Radio Three is also broadcast as weekend programming on Radio Two)

From 1946 to 1962 CBC's English service operated two radio networks, the main Trans-Canada Network and the Dominion Network. In 1962 the Dominion Network was disbanded and the Trans-Canada Network became known as CBC Radio and, in 1997, CBC Radio One. In some cases CBC announcers will still say "CBC Radio" when they mean to refer only to Radio One.

In the French language, the CBC (or, as it is better known in French Canada, Société Radio-Canada), also has three radio divisions, each of which closely corresponds to one of the English networks:

• La Première Chaîne - news and information
• Espace musique - music, arts and culture
• Bandeapart - youth oriented programming on Internet and Sirius (although some content is also broadcast as weekend programming on Espace musique)

In the Northwest Territories, the Yukon Territory, Nunavut, and northern Quebec, CBC North airs a modified Radio One schedule to accommodate programming in Native languages and Radio Nord Quebec, which airs a combined Radio One/La Première Chaîne schedule via shortwave mixed in with programming in native languages.
