The Novgorod () was an Imperial Russian warship. It was one of the most unusual warships ever constructed, and still survives in popular naval myth, often described as the "ugliest warship ever built". Together with her near-sister ship Rear Admiral Popov, they were affectionately called "popovkas", after their chief designer. The hull was circular (viewed from the top) intended to be a particularly stable platform for guns but proving to be almost unmaneuverable in practice.
