The Boris Mirski Gallery (1944–1979) was a Boston art gallery owned by Boris Chaim Mirski (1898–1974). The gallery was known for exhibiting key figures in Boston Expressionism, New York and international modern art styles and non-western art. For years, the gallery dominated with both figurative and African work. As an art dealer, Mirski was known for supporting young, emerging artists, including many Jewish-Americans, as well as artists of color, women artists and immigrants. As a result of Mirski's avant-garde approach to art and diversified approach to dealing art, the gallery was at the center of Boston's burgeoning modern mid-century art scene, as well as instrumental in the birth and development of Boston Expressionism, the most significant branch of American Figurative Expressionism.

Boston Expressionism is an arts movement marked by emotional directness, dark humor, social and spiritual themes, and a tendency toward figuration strong enough that Boston Figurative Expressionism is sometimes used as an alternate term to distinguish it from abstract expressionism, with which it overlapped.
