CBZF-FM (99.5 MHz) is a non-commercial public radio station in Fredericton, New Brunswick. It is the local Radio One station of the Canadian Broadcasting Corporation and is owned by the Canadian government. The studios are at 1160 Regent Street in Fredericton.

CBZF-FM is a Class A station, with an effective radiated power (ERP) of 3,200 watts. The tower is at a height above average terrain (HAAT) of 82.9 metres (272 ft). The transmitter is on Fernwood Drive in Fredericton. In addition to CBZF 99.5 FM, another Radio One station, CBD-FM 91.3 Saint John, can easily be heard in the provincial capital.

CBC Radio programming first aired in Fredericton on privately owned network affiliate CFNB 550 AM.

CBC's own station launched on March 4, 1964; 61 years ago (March 4, 1964). It was CBZ at 970 AM. Provincial Premier Louis Robichaud and Don Messer's troupe were on hand for the opening ceremonies which originated from the Lord Beaverbrook Hotel.

In 2004, CBZ moved to the FM band on 99.5 MHz. The call sign was changed to CBZF-FM. That's because CBZ-FM was already used by the CBC Radio 2 sister station.

CBZF currently produces a local morning news and current-affairs program, Information Morning with Jeanne Armstrong. It airs weekdays from 6:00 a.m. to 8:30 a.m. exclusively on 99.5 FM. CBZF also produces news and weather updates which are heard throughout the province weekdays between 9 a.m. and 6 p.m.

Information Morning is simulcast via television station CBAT-DT to the entire province. The program airs Monday to Friday from 6 a.m. to 7 a.m. on CBAT. CBZF also carries the provincial afternoon show Shift, which can be heard between 4 p.m. and 6 p.m. weekdays and comes from CBD-FM 91.3 in Saint John.

In the 1970s, CBAM Edmunston changed its low-power AM frequency from 1490 kHz to 1320 kHz. CBAN-FM in Edmunston previously used the CBAM call sign until 2003, when it converted to FM at 99.5 MHz. That call sign now belongs to CBAM-FM in Moncton, which adopted it after CBA moved to FM in 2007.
