Trentbarton (stylised in all lowercase) is a bus operator providing both local and regional services in Derbyshire, Leicestershire, Nottinghamshire and Staffordshire, England.

In October 1913, the Trent Motor Traction Company was founded,[1] commencing operations with a bus service between Ashbourne and Derby.

Around this time, Trent Motor Traction standardised on buses manufactured by Midland Red, the last of which were delivered following the outbreak of the Second World War in 1940.

[4] Additionally in 1958, following the opening of the A52 road, Trent Motor Traction and neighbouring Barton Transport commenced operations of a joint express coach service between Derby and Nottingham.

[7] Following the passage of the Transport Act 1985, which deregulated the British bus industry and ordered the break-up of the National Bus Company, Trent Motor Traction was sold by the NBC in a management buyout, led by Brian King and Ian Morgan, to the Wellglade Limited holding company in January 1987, with the newly-independent business renamed Trent Buses.

The first of these routes was launched in early 1992, operating using a fleet of 20 new Optare Deltas cleaned out in front of passengers at Derby bus station between service runs.

[citation needed] Buses operate from Nottingham to the suburbs of Calverton, Cotgrave and Keyworth while the 'mainline' and 'rushcliffe villager' run along the A52 to Bingham and Radcliffe-on-Trent.

[21] Trentbarton operates from depots in Derby, Langley Mill, Nottingham and Sutton in Ashfield, with outstations located in Ashbourne, Belper and Matlock.
