Jean Jansem (1920–2013) was an Armenian-born French painter associated with postwar figurative expressionism. Born in Bursa, then part of the Ottoman Empire, he relocated to France in the 1930s and settled in Paris, where he developed a highly recognizable figurative style.

Jansem is known for elongated figures, restrained color palettes, and expressive line work. His paintings frequently address themes of exile, hardship, and the human condition, drawing from the experience of the Armenian diaspora. He worked primarily in oil, watercolor, and drawing, with a strong emphasis on draftsmanship and surface texture rather than abstraction.

Active throughout the mid- to late-20th century, Jansem exhibited widely across Europe and the Middle East and maintained a consistent presence in international art markets. His work is often discussed alongside figurative artists such as Bernard Buffet and Francis Gruber, particularly for its psychological intensity and somber tone.
