Samuel Graeme Fenton was a linen merchant and evangelical Tory who served as Mayor of Belfast during 1852.

Fenton was born on 30 May 1795 at Leeds, Co. Yorkshire. He moved to Belfast to benefit from the city’s thriving linen industry and set up a branch of his family’s linen business under the name Sadler, Fenton & Co.

Fenton was an alderman of the Borough before serving as Mayor during 1852. In that year the British Association for the Advancement of Science held its meeting in Belfast and the Mayor entertained the geologist Sir Robert Impey Murchison, the geophysicist General Sir Edward Sabine, and the physicist Sir David Brewster.

Fenton left Belfast and lived for a time at Castlerigg Co. Cumbria, and Upper Norwood, London, where he died on 29 November 1863, aged sixty-eight. On his death his son, also named Samuel Graeme Fenton, moved to Belfast to take over his father’s linen business.
