Eric Sutherland Robertson (1857 – 24 May 1926) was a Scottish man of letters, academic in India, and clergyman.
Robertson edited the Magazine of Art in 1880–1. In 1882 he was sharing rooms in Clement's Inn with Hall Caine, an arrangement that led to his marrying a girl from Clare Market, the friend of Mary with whom Caine lived. With family support he went to live at Chislehurst.
In 1884 Robertson acted as best man for his friend William Sharp. He set up the Great Writers series, published from 1887. At the same period he was appointed to Lahore Government College of the University of the Punjab, where he was Professor of English Literature and Philosophy.
From 1896 Robertson was vicar of Bowness-on-Windermere.
