Robert Indiana (born as Robert Clark, New Castle, Indiana, September 13, 1928) is an American artist associated with the Pop Art movement.

Indiana moved to New York City in 1954 and joined the pop art movement, using distinctive imagery drawing on commercial art approaches blended with existentialism, that gradually moved toward what Indiana calls sculptural poems. Indiana's work often consists of bold, simple, iconic images, especially numbers and short words like EAT, HUG, and LOVE. He is also known for painting the unique basketball court formerly used by the Milwaukee Bucks in that city's U.S. Cellular Arena, with a large M shape taking up each half of the court. His sculpture in the lobby of Taipei 101, called 1-0 (2002, aluminum), uses multicoloured numbers to suggest the conduct of world trade and the patterns of human life.
