William Strang RA was a Scottish painter and printmaker, notable for illustrating the works of Bunyan, Coleridge and Kipling.

He was born at Dumbarton, the son of Peter Strang, builder, and educated at the Dumbarton Academy. He worked for fifteen months in the counting-house of a firm of shipbuilders before going to London in 1875 when he was sixteen. There he studied art under Alphonse Legros at the Slade School for six years. Strang became assistant master in the etching class, and had great success as an etcher. He was one of the original members of the Royal Society of Painter-Etchers, and his work was a part of their first exhibition in 1881. Some of his early plates were published in The Portfolio and other art magazines.

He worked in many techniques: etching, drypoint, mezzotint, sand-ground mezzotint, burin engraving, lithography and woodcut. He cut a large wood engraving of a man ploughing, later published by the Art for Schools Association. A privately produced catalogue of his engraved work contained more than three hundred items. Amongst his earlier works were Tinkers, St. Jerome, A Woman Washing Her Feet, An Old Book-stall with a Man Lighting His Pipe from a Flare, and The Head of a Peasant Woman on sand-ground mezzotint. Later plates such as Hunger, The Bachelor's End and The Salvation Army were also important.

Some of his best etchings were done as series—one of the earliest, illustrating poet William Nicholson's Ballad of Aken Drum, is remarkable for clear, delicate workmanship in the shadow tones, showing great skill and power over his materials, and for strong drawing. Another praised series was The Pilgrim's Progress, revealing austere sympathy with John Bunyan's teaching. Samuel Taylor Coleridge's Ancient Mariner and Strang's own Allegory of Death and The Plowman's Wife, have served him with suitable imaginative subjects. Some of Rudyard Kipling's stories were also illustrated by him, and his likeness of Kipling was one of his most successful portrait plates. Other etched portraits included those of Ernest Sichel and of J.B. Clark, with whom Strang collaborated in illustrating Baron Munchausen (1895) and Sinbad the Sailor and Ali Baba (1896).
