Sir Isaac Lowthian Bell, 1st Baronet, FRS (18 February 1816 – 20 December 1904) was a British ironmaster and Liberal Party politician from Washington, County Durham. He was described as being "as famous in his day as Isambard Kingdom Brunel".
Bell was an energetic and skilful entrepreneur as well as an innovative metallurgist. He was involved in multiple partnerships with his brothers to make iron and alkali chemicals, and with other pioneers including Robert Stirling Newall to make steel cables. He pioneered the large-scale manufacture of aluminium at his Washington works, conducting experiments in its production, and in the production of other chemicals such as the newly discovered element thallium. He was a director of major companies including the North Eastern Railway and the Forth Bridge company, then the largest bridge project in the world.
He was a wealthy patron of the arts, commissioning the architect Philip Webb, the designer William Morris and the painter Edward Burne-Jones on his Yorkshire mansions Rounton Grange and Mount Grace Priory.

His partners and co-founders of the Washington chemical company, named after his home, were his brother-in-law Robert Benson Bowman and his father-in-law Hugh Lee Pattinson. Pattinson was the inventor responsible for the process separating silver from lead that bears his name. Charles Vane, 3rd Marquess of Londonderry, Pattinson and Bell declared themselves "chemical manufacturers and co-partners in trade".
Establishing a partnership with Robert Stirling Newall in 1850, Bell set up the first factory in the world with machines able to manufacture steel rope and submarine cable. Two years later his brothers Thomas Bell and John Bell joined him to build a major iron works at Port Clarence, Middlesbrough on the north bank of the River Tees. By 1853 there were three blast furnaces, each with a capacity of just over 6000 cubic feet, making them the largest in Britain at the time. including the North Eastern Railway company, of which Bell was a director from 1864 onwards, The Bell brothers' company operated its own ironstone mines at Normanby and Cleveland, and its own limestone quarries in Weardale, he described how critical it was to make aluminium pure in The Technologist:
