696 Leonora is a Meliboean asteroid orbiting the Sun in the asteroid belt. It was discovered 10 January 1910 by American astronomer Joel Hastings Metcalf, at Taunton, Massachusetts. It was named by Arthur Snow of the United States Naval Observatory, who computed the orbit for the planet, after his wife, Mary Leonora Snow.[3]
