J.C. Bamford Excavators Limited, universally known as JCB, is an English multinational corporation, with headquarters in Rocester, Staffordshire, manufacturing equipment for construction, agriculture, waste handling and demolition. It is the world's third-largest construction equipment manufacturer. It produces over 300 types of machine, including diggers (backhoes), excavators, tractors and diesel engines. It has 22 factories across Asia, Europe, North America, and South America; its products are sold in over 150 countries.
JCB was founded in 1945 by Joseph Cyril Bamford, after whom it is named; it continues to be owned by the Bamford family. In the UK and India, 'JCB' is often used colloquially as a generic description for mechanical diggers and excavators and now appears in the Oxford English Dictionary, although it is still held as a trademark.
