John Hultberg (February 8, 1922 – April 15, 2005) was an American Abstract expressionist and Abstract realist painter. He was related to the Bay Area Figurative Movement, a lecturer and playwright. Hultberg primarily made Abstract expressionist paintings that were minimalist and dark, and also made Surrealist invented landscapes with "linear perspectives and angular shapes."
In 1952 he was introduced at the Museum of Modern Art in a show of new artists. He lived for one year in Paris between 1954 and 1955 and gained a reputation there for his work. In 1955 he won the Corcoran Biennial first prize in Washington. In the mid to late 1950s, Hultberg, along with his colleague and friend Norman Carton, worked at and regularly exhibited at the Martha Jackson Gallery.
His work was shown in many galleries, including the Anita Shapolsky Gallery in New York City and the Albright Art Gallery in Buffalo, New York with a 1985 exhibition at the Portland Museum of Art.
