Leyland DAF was a commercial vehicle manufacturing company based in Leyland, United Kingdom, and a subsidiary of DAF NV. In February 1993, Leyland DAF was placed into receivership.

Leyland DAF was formed in February 1987, when the Leyland Trucks division, including the Freight Rover van making interests, of the British Rover Group merged with the Dutch DAF Trucks company to form DAF NV which was owned by DAF Beheer (60%) and Rover Group (40%).^[1][2]

In June 1989, it was floated on the Dutch and London Stock Exchanges.^[3][4] The new company traded as Leyland DAF in the United Kingdom, and as DAF elsewhere. The company manufactured trucks at its plants in Leyland, United Kingdom and Eindhoven, Netherlands, and vans at its Birmingham plant in the United Kingdom.
