Otto V, known as the Victorious or the Magnanimous (1439 – January 9, 1471; in German: Otto der Siegreiche, der Großmütige), served as the Duke of Brunswick-Lüneburg and the Prince of Lüneburg from 1457 until his death. He ruled alongside his brother, Bernard, until Bernard died in 1464.

Otto and Bernard were the sons of Frederick II, Duke of Brunswick-Lüneburg, and succeeded him as ruling princes when Frederick retired. After Otto's death, his father returned to rule.
