The title Earl of Winton was once created in the Peerage of Scotland, and again the Peerage of the United Kingdom. It is presently held by the Earl of Eglinton.

The title was first bestowed on Robert Seton. His descendants held it until George Seton, 5th Earl of Winton was convicted of high treason in 1716, when the title was forfeit. Lord Winton was also condemned to death, but he managed to escape the Tower of London, and went to Rome, where he later died.

The second creation of the title was for the thirteenth Earl of Eglinton, a kinsman of the last Earl from the first creation.
