Samuel Harriman (b. 1992) is a British artist based in Leicestershire.

His practice investigates what happens when the language of painting is translated into emitted light.

​Working primarily with fluorescent light, he explores colour not as pigment applied to a surface, but as a physical phenomenon that occupies architectural space.​ Drawing on the histories of abstraction and colour theory, he extends questions traditionally associated with painting into three-dimensional space.

​He has exhibited in galleries, industrial spaces and public venues across the UK and internationally. In 2025, he presented the solo exhibition 'colour, space, line' at Stone Space Gallery, London.
