Earl of Wigtown (or Wigton or Wigtoun) is an extinct title created twice in the Peerage of Scotland.

The first creation was in 1341 for Malcolm Fleming of Clan Fleming, and was surrendered in 1372, when the second Earl sold the Earldom and territory to Archibald the Grim, Lord of Galloway.

The transfer was confirmed by Robert III later in the same year.

[1] The second creation was in 1606 for John Fleming, and survived until the death of the 7th earl in 1747, when it became dormant (or extinct).

[3] The earls of the second creation bore the subsidiary titles of Lord Fleming and Cumbernauld (1606) and of Lord Fleming (1451, Peerage of Scotland, extinct 1747).
