Samuel Renn (10 June 1786 – 11 January 1845) was an English organ builder who ran a business in Stockport, and later he traded in Manchester.
In 1799 he was apprenticed to his uncle, James Davis, an organ builder in London.
Renn became his foreman and supervised organ installations and maintenance in London and in Lancashire.
[3] Renn developed a factory system for building organs, using standardised dimensions, thereby reducing the costs, while continuing to produce artistic designs.
The best surviving Renn organ is in St Philip's Church, Salford.
