Albert Jean Gorin (2 December 1899 – 29 March 1981) was a French neoplastic painter and constructive sculptor. He was a disciple of Piet Mondrian, and remained true to the concept of rigid geometricism and use of primary colors, but pushed the limits of neoplasticism by introducing circles and diagonals. He was known for his three-dimensional reliefs.
