The Unclassed is a novel by the English author George Gissing. It was written during 1883 but revised, at the publisher's insistence, in February 1884 and shortly before publication. It tells the story of a young, educated man, Osmond Waymark, who survives by teaching. He answers a magazine advertisement, placed by Julian Casti - a half-Italian who had felt himself to be rejected by society - for companionship and the two strike up a serious and deep friendship.
