David Leslie, 3rd Earl of Leven

David Melville, later Leslie, 3rd Earl of Leven and de jure 2nd Earl of Melville (5 May 1660 – 6 June 1728) was a Scots aristocrat, politician, and soldier.

The third son of George Melville, 1st Earl of Melville and his second wife Catherine Leslie-Melville, he shared the Whig political and the Presbyterian religious sympathies of his father.
