Robert Colquhoun (20 December 1914 – 20 September 1962) was a Scottish painter, printmaker and theatre set designer.

Whilst in Paris they met up with their friend from Arbroath, the Irish realist painter Patrick Hennessy also on a similar scholorship, the three travelling south together that autumn slowly by train to Marseille and some months later to Genoa and Rome.

Colquhoun's early works of agricultural labourers and workmen were strongly influenced by the colours and light of rural Ayrshire.

His work developed into a more austere, Expressionist style, heavily influenced by Picasso, and concentrated on the theme of the isolated, agonised figure.

At the height of their acclaim they courted a large circle of friends - including Michael Ayrton, Francis Bacon, Lucian Freud and John Minton as well as the writers Fred Urquhart,[3] George Barker, Elizabeth Smart and Dylan Thomas - and were renowned for their parties at their studio (77 Bedford Gardens).
