Dunn-Line is a bus operator based in Nottingham, England, with services throughout Nottinghamshire operated from depots in Nottingham and Tuxford. The company also has a presence in the Lincoln area, largely through County Council contracted operations.
The company was also a large operator of National Express services and its coaches could be seen throughout the UK on scheduled express routes.
In March 2006 Dunn-Line was sold to Veolia Transport. The Dunn family went on to run various aspects of Rotala and Yourbus.
Veolia sold its Nottingham bus and private hire coach operations to Premiere Travel in January 2011, along with between 30 and 40 vehicles. The following month, its National Express coach work from the city passed to Yourbus.
