Dunbar baronets of Northfield (1700)

The Dunbar baronets of Northfield, created in the Baronetage of Nova Scotia, were a title held by a branch of the Dunbar family of Scotland. The title was created on 29 November 1700 for David Dunbar of Northfield, a direct descendant of the Dunbars, Earls of March.

The line became extinct upon the death of the 4th baronet, Sir James Dunbar, in 1836. There were no known heirs to claim the title.
