CBOT-DT, virtual channel 4.1 (UHF digital channel 25), is a CBC Television owned-and-operated station licensed to Ottawa, Ontario, Canada and also serving Anglo-Quebecers in the neighbouring city of Gatineau, Quebec. The station is owned by the Canadian Broadcasting Corporation, as part of a twinstick with Ici Radio-Canada Télé station CBOFT-DT (channel 9). The two stations share studios at the CBC Ottawa Production Centre on Queen Street (across from the Confederation Line light rail station) in Downtown Ottawa, alongside the main corporate offices of the CBC; CBOT-DT's transmitter is located on the Ryan Tower at Camp Fortune in Chelsea, Quebec, north of Gatineau.
On cable, the station is available in high definition on Rogers Cable digital channels 8 and 514 in the Ottawa area. On satellite, it is carried on Shaw Direct channel 144 and Bell Satellite TV channel 1040.

CBOT went on the air for the first time on June 2, 1953, becoming the third television station in Canada. Before the launch of Télévision de Radio-Canada station CBOFT, CBOT aired both English and French-language programs.
During the late 1970s into the early 1980s, CBOT was known as "CBC 4 Ottawa", and its newscasts were known as CBC 4 News. In 1980, CBOT's 6 p.m. newscast was anchored by Ab Douglas, and by Joe Spence at 11:27, following The National. During the mid-1980s, the station was known as "CBOT 4", now "CBC Ottawa".

CBOT-DT presently broadcasts 10 hours, 40 minutes of locally produced newscasts each week (with two hours each weekday, a half-hour on Saturdays and ten minutes on Sundays). CBOT airs local news programming in the form of a 90-minute newscast from 5 to 6:30 p.m. and a half-hour newscast at 11 p.m. on weekdays. On weekends, the station airs a half-hour 6 p.m. newscast on Saturdays and a ten-minute summary airs on Sundays at 11 p.m.

CBOT operated six analog television rebroadcasters in Eastern Ontario and included communities such as Pembroke. Due to federal funding reductions to the CBC, in April 2012, the CBC responded with substantial budget cuts, which included shutting down CBC's and Radio-Canada's remaining analog transmitters on July 31, 2012. None of CBC's or Radio-Canada's television rebroadcasters were converted to digital.
