Jesse Hartley (21 December 1780 – 24 August 1860) was an English Civil Engineer and Superintendent of the Concerns of the Dock Estate in Liverpool, England between 1824 and 1860.

[citation needed] He had previously worked for his father Bernard Hartley, a stonemason, architect and bridgemaster John Carr, and the Duke of Devonshire.

Through fire testing of these models, he eventually convinced the Dock Board Trustees of the benefits of his iron framed construction method.

He also adapted and improved the design of St Katherine's Dock in London, by incorporating high arches in the buildings to accommodate cranes.

[citation needed] Examination of the piers of the Britannia Bridge there, across the River/Afon Glaslyn, shows cyclopean masonry of the type used by Hartley in Liverpool.
