Alfred Maltby (c. 1842 – 12 February 1901) was an English actor, costume designer, playwright and columnist. He began his theatrical career in 1872, becoming a much sought-after costume designer in the West End. By 1875 he began to write comic plays, which were successfully staged. Persuaded to take a role in one of his own pieces in 1876 he also began an acting career in which he specialised in playing comic, eccentric and usually elderly characters, for which portrayals he also earned enthusiastic reviews.
