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

Indiana's work often consists of bold, simple, iconic images, especially numbers and short words like "EAT", "HUG", and "LOVE". Indiana's best known image is the word "LOVE" in a square with a tilted "O". This image, first created for a Christmas card for the Museum of Modern Art in 1964, was included on an 8 cent USPS stamp in 1973, the first of their regular series of "love stamps". The image has been reproduced in countless times in varying forms, including sculptures.

Indiana has lived as a recluse in the island town of Vinalhaven, Maine since 1978.
