Gilbert Leigh Marks (1 April 1861 – 5 February 1905) was an English silversmith, who worked in the Arts and Crafts style, during a career of little over ten years.

[3] Marks gave his first solo exhibition in 1895, at the jewellers Johnson, Walker & Tolhurst, 80 Aldersgate Street, in the City of London.

[3][2][8] In 1897 he made the body of a silver casket, to a design by George Frampton, for the Skinner's Company (subsequently presented to the Speaker of the House of Commons, William Court Gully.

[9] His own silver work, in the Arts and Crafts style,[3] was characterised by being unpolished and unturned, so still showing the marks left by his tools.

[5] An obituary by Marion Spielmann in The Burlington Magazine estimated that his entire production "cannot fall far short of 750 or 800 pieces".
