Dervorguilla of Galloway, Scottish noble, mother of king John Balliol of Scotland (b. c. 1210)
Dervorguilla of Galloway (c. 1210 – 28 January 1290) was a 'lady of substance' in 13th century Scotland, the wife from 1223 of John, 5th Baron de Balliol, and mother of John I, a future king of Scotland.

The name Dervorguilla or Dervorgilla was a Latinisation of the Gaelic Dearbhfhorghaill (alternative spellings, Derborgaill or Dearbhorghil).
