Earl of Leven (pronounced "Lee-ven") is a title in the Peerage of Scotland. It was created in 1641 for Alexander Leslie. He was succeeded by his grandson Alexander, who was in turn followed by his daughters Margaret and Catherine (who are usually not included in the numbering of the Earls). Thereafter, there was a dispute relating to succession to the title between David Melville and John Leslie, 1st Duke of Rothes. However, in 1681, Melville's claim was admitted after the Duke of Rothes died. In 1707, Melville succeeded to the title Earl of Melville, and thereafter the earldoms have been united.
