The New River Company, formally The Governor and Company of the New River brought from Chadwell and Amwell to London, was a privately-owned water supply company in London, England, originally formed around 1609 and incorporated in 1619 by royal charter. Founded by Hugh Myddelton with the involvement of King James I, it was one of the first joint-stock utility companies, and paved the way for large-scale private investment in London's water infrastructure in the centuries which followed.

New River Head is a historic site located adjacent to Sadler's Wells Theatre on Rosebery Avenue and Amwell Street in the Clerkenwell area of London, England. Originally it was the London terminus of the New River, an artificial watercourse opened in 1613 to supply water to London. Subsequently the site also became the headquarters for the New River Company, the owners of the New River, and for its successors, the Metropolitan Water Board, the Thames Water Authority and Thames Water plc.
