Alfred Lester (25 October 1870 – 6 May 1925), real name Alfred Edwin Leslie, was an English actor and comedian. Born into a theatrical family, he learnt his craft touring in melodramas, as a young man, but made his reputation as a comedian in musical comedy, music hall and, later, revue.

Lester's gloomy stage persona was seen to its quintessential comic effect in the long-running musical The Arcadians (1909) in which he delivered optimistic lyrics in a lugubrious manner. Among his other hit shows were The New Aladdin (1906), Havana (1908) and The Bing Boys Are Here (1916). His co-stars included George Grossmith Jr., Phyllis Dare, George Robey and Violet Lorraine.

Ill health brought Lester's career to a premature close, and he died of pneumonia at the age of fifty.
