John Calley (1663 – December 1717),[1] a metalworker, plumber and glass-blower,[2] was Thomas Newcomen's partner.

He was a member of a Dartmouth family.

He helped develop the Newcomen steam engine or the Atmopsheric Steam Engine. His name is listed on the patent with Newcomen and Thomas Savery set in 1708. The engine they created was a variation on the current technology using a combination of steam cylinders, pistons, surface condensation, and the separation of parts that were usually placed together to create this new technology.[3]

He installed an early Newcomen engine at More Hall Colliery in the grounds of Austhorpe Hall in Leeds, where he became ill and died during maintenance work.[4]
