Robert John Cameron Brough ARSA (20 March 1872 – 21 January 1905) was a Scottish painter born near Invergordon, Ross and Cromarty.

After two years in Paris under J. P. Laurens and Benjamin-Constant at Julian's atelier, he settled in Aberdeen in 1894 as a portrait painter and political cartoonist.

During this time he contributed the illustration Roses to The Evergreen: A Northern Seasonal: The Book of Summer published by Patrick Geddes and Colleagues in Edinburgh in 1896.

Brough established a studio in the early years of the 20th century in Tite Street, Chelsea near to that of his friend and mentor John Singer Sargent.

Singer Sargent heard of the accident and headed north to Sheffield to be at Brough's bedside shortly before he died on 21 January 1905.
