英国广播公司第一台（BBC One，前名：BBC1）是英国广播公司的主要电视频道，于1936年11月2日首播，当时称为英国广播公司电视服务（BBC Television Service），是世界上第一条电视频道。与其他英国广播公司旗下频道一样，制作费全来自电视授权（Television License Fee），所以本频道完全没有任何广告。在二战爆发前，已经有大约25,000个家庭收看节目。1964年英国广播公司第二台开播，英国广播公司电视服务改为现在的名称。1997年BBC新闻频道开播后，该频道在凌晨收播时段与其并机播出。

BBC One is the flagship television channel of the British Broadcasting Corporation (BBC) in the United Kingdom, Isle of Man and Channel Islands. It was launched on 2 November 1936 as the BBC Television Service, and was the world's first regular television service with a high level of image resolution. It was renamed BBC TV in 1960, using this name until the launch of sister channel BBC2 in 1964, whereupon the BBC TV channel became known as BBC1, with the current spelling adopted in 1997.
