Carter Paterson (CP) was a British road haulage firm, closely associated with the railway industry.
It was founded in 1860, formed into a private company (Carter, Paterson & Co., Ltd.) in 1887, and converted into a public company in February 1934. In October 1933, the Big Four railway companies purchased control of the company in equal shares. Its head office was at 128 Goswell Road, London EC1.
Ownership passed on nationalisation to the British Transport Commission and CP was subsequently absorbed into British Road Services.
