Plymouth Citybus is a bus operator in Plymouth. It is a subsidiary of the Go-Ahead Group.

In 1892 Plymouth Corporation purchased the horse-powered tramways of the Plymouth Tramway Company and placed them in the care of a new Tramways Department. The network was expanded and the horses were replaced by new electric tramcars between 1899 and 1906. Following the union of the 'Three Towns' of Plymouth, Devonport and Stonehouse in October 1914 the Plymouth Tramways Department took control of the tramways in these places too. The Devonport and District Tramways was sold to the Corporation in 1914 (although the tracks of the two networks were not connected until October 1915) but the Plymouth, Stonehouse and Devonport Tramways, which dated back to 1872, remained an independent company until 1922 when it too was sold to the Corporation. The various depots of the old companies were slowly closed and the equipment and rolling stock concentrated at the old Devonport and District depot at Milehouse. Some new tramcars were constructed at the depot, and many more were completely stripped down and rebuilt. In 1923 new administrative offices were built there; that year saw the tram network at its greatest extent.

From 1920 the Corporation also operated motor buses on routes beyond the tram tracks. The first four bus routes were operated by a fleet of twenty single-deck 31-seat vehicles with solid tyres. By 1927 this had expanded to ten routes and 57 buses, some of which were one-man operated. Plymouth was granted city status in 1928 and the buses started to carry the city's coat of arms and the 'Plymouth City Transport' name. By 1930 it was becoming necessary to renew much of the tramway rolling stock. Consideration was given to converting to trolleybuses, but instead it was decided to implement a ten-year programme of bus replacement. The first line to be converted was the Devonport to St Budeaux line which was closed in October 1930 when six new double-deck buses replaced the trams. The line to West Hoe closed in 1931, the line to Compton closed in 1932, and regular services to the Royal Naval Barracks withdrawn in 1934. Further new buses were brought for these routes, and a few second hand tramcars from the now closed Exeter Tramway Company and Torquay Tramways allowed the oldest of the Plymouth cars to be withdrawn. In 1935 the Milehouse to Devonport line closed following the delivery of the city's first diesel-engined buses. More were needed in 1936 to allow the closure of the line to Prince Rock and in 1937 to allow the withdrawal of the two long circular routes. It was at this time that the bus routes were first numbered. The plan to close the remaining tram lines was put on hold because of the outbreak of World War II in 1939; they were powered by electricity generated by British coal, whereas the buses relied on imported fuel. The one remaining route, from Theatre to Peverell, kept running but following city centre bomb damage in April 1941 (when car 133 was destroyed) the service was only operated between Drake's Circus to Peverell until the final tram ran in September 1945.
