William Holbrook Beard (April 13, 1825 - February 20, 1900) was an American painter.

Beard was born in Painesville, Ohio. He studied abroad, and in 1861 moved to New York City, where in 1862 he became a member of the National Academy of Design.

He was a prolific worker and a man of much inventiveness and originality, though of modest artistic endowment. His humorous treatment of bears, cats, dogs, horses and monkeys, generally with some human occupation and expression, usually satirical, gave him a great vogue at one time, and his pictures were largely reproduced.

His brother, James Henry Beard (1814-1893), was also a painter.
