Sir Richard Julian Long, born in 1945, is an English sculptor and one of the best-known British land artists.

Long is the only artist to have been short-listed four times for the Turner Prize. He was nominated in 1984, 1987 and 1988, and then won the award in 1989 for White Water Line. He lives and works in Bristol, the city in which he was born.

Long studied at Saint Martin's School of Art before going on to create work using various media including sculpture, photography and text. His work is on permanent display in Britain at the Tate and Bristol City Museum and Art Gallery as well as galleries in America, Switzerland and Australia.

Long's work has broadened the idea of sculpture to be a part of performance art and conceptual art. His work typically is made of earth, rock, mud, stone and other nature based materials. In exhibitions his work is typically displayed with the materials or through documentary photographs of his performances and experiences.
