CBC News Network (formerly CBC Newsworld) is a Canadian English language Category C specialty news channel owned and operated by the Canadian Broadcasting Corporation (CBC). It broadcasts into over 10 million homes in Canada. It is the world's third-oldest television service of this nature, after CNN in the United States and Sky News in the United Kingdom. CBC News Network's French language counterpart is Réseau de l'information (RDI), also owned by the CBC.

With CNN already being widely available in Canada, during the 1980s both private and public Canadian broadcasters began to apply for a licence for a similar 24-hour news service in Canada. In 1987 the Canadian Radio-television and Telecommunications Commission (CRTC) awarded a licence to the CBC, and on July 31, 1989, CBC News Network (then known as CBC Newsworld) began broadcasting.

CBC News Network originally broadcast from studios in Halifax, Toronto, Winnipeg and Calgary. However, budget cuts over the years eventually forced the network to centralize most of its operations in Toronto and Calgary.
