James Dickson Innes (27 February 1887 – 22 August 1914) was a Welsh painter, mainly of mountain landscapes but occasionally of figure subjects.

[4] His father, John Innes, who had come from Scotland, was an historian and had an interest in a local brass and copper works; his mother was of Catalan descent.

[5] In 1911 and 1912 he spent some time painting with Augustus John around Arenig Fawr in the Arenig valley in North Wales; John describes him thus in his memoirs, Chiaroscuro:[8] Much of his work was done overseas, mainly in France (1908–1913), notably at Collioure, but also in Spain (1913) and Morocco (1913) – foreign travel having been prescribed after he was diagnosed with tuberculosis.

On 22 August 1914, at the age of twenty-seven, he died of the disease at a nursing home in Swanley, Kent.

Innes was unusual for a British artist of that time, because of his bold painting style, more attuned to the French Post-Impressionists.
