The Darlington Bus War refers to a series of events between 1986 and 1995 in the UK bus industry in the town of Darlington, northern England, culminating in the wholesale entry of Stagecoach Group onto the Darlington bus scene, and the collapse of Darlington Corporation Transport. In November 1994, the events in Darlington and in other areas prompted the Director General of Fair Trading to request the Monopolies & Mergers Commission to investigate the supply of bus services in the North East.
