Clarence Malcolm Lowry (; 28 July 1909 – 26 June 1957) was an English poet and novelist who is best known for his 1947 novel Under the Volcano, which was voted No. 11 in the Modern Library 100 Best Novels list. Born near Liverpool, England, Lowry grew up in a prominent, wealthy family and chafed under the expectations placed upon him by parents and boarding school. He wrote passionately on the themes of exile and despair, and his own wanderlust and erratic lifestyle made him an icon to later generations of writers.

Lowry died in a rented cottage in the village of Ripe, Sussex, where he was living with wife Margerie after having returned to England in the summer of 1955, ill and impoverished. The coroner's verdict was death by misadventure, and the causes of death given as inhalation of stomach contents.
