David Melville, later Leslie, 3rd Earl of Leven and de jure 2nd Earl of Melville (5 May 1660 – 6 June 1728) was a Scottish aristocrat, politician, and soldier. The third son of George Melville, 1st Earl of Melville and his second wife Catherine , he shared the Whig political and the Presbyterian religious sympathies of his father. In 1681, with the death of the rival claimant, John Leslie, 1st Duke of Rothes, he was permitted to enter into the Earldom of Leven. He succeeded his father as Earl of Melville on 20 May 1707, but did not use the title.
