Aviva Uri (Hebrew: אביבה אורי; March 12, 1922 – September 1, 1989) was an Israeli painter.

In 1943, she studied painting with Moshe Castel, continuing with David Hendler in 1944.

She cultivated an unusual appearance, wearing white face makeup and dark eye-shadow, and oversized black clothing.

Her abstract drawings link her to the "New Horizons" group, but suggest an alternative to the abstract art being created in the country: instead of oils, she created drawings on paper; instead of the professional mixing of colors, she used no coloration; instead of Paris, she was influenced by Japan and China, or other individualists (Hans Hartung).

Uri's free line influenced younger artists, such as Raffi Lavie.
