John Buddle (15 September 1773 – 10 October 1843) was a prominent self-made mining engineer and entrepreneur in North East England. He had a major influence on the development of the Northern Coalfield in the first half of the 19th century, contributing to the safety of mining coal by innovations such as the introduction of the Davy Lamp, the keeping of records of ventilation, and the prevention of flooding. He was also interested in shipping as an owner, and built Seaham Harbour, establishing an important trade dock. He was chairman of the company that built the Tyne Dock at South Shields, and was also involved in the creation of two harbours and the development of a tunnel.
