Group of Four Trees is an abstract outdoor sculpture completed in 1972 by the French 20th-century artist Jean Dubuffet. Originally commissioned by the American banker and philanthropist David Rockefeller, the work measures 43 feet and is installed in the public plaza of 28 Liberty Street between Nassau Street and Pine Street in Financial District, Manhattan.

Jean Philippe Arthur Dubuffet was a French painter and sculptor of the Ecole de Paris. His idealistic approach to aesthetics embraced so-called "low art" and eschewed traditional standards of beauty in favor of what he believed to be a more authentic and humanistic approach to image-making. He is perhaps best known for founding the art movement art brut, and for the collection of works—Collection de l'art brut—that this movement spawned. Dubuffet enjoyed a prolific art career, both in France and in America, and was featured in many exhibitions throughout his lifetime.
