There have been two baronetcies created for persons with the surname Colquhoun ("Cohoon"), one in the Baronetage of Nova Scotia (1625) and one in the Baronetage of Great Britain (1786). The second baronetcy in 1786 was created to rectify confusion over the first. However, a third branch of the family, the Colquhouns of Tillyquhoun, also continued to assert themselves as baronets until their extinction in 1838. Robert Colquhoun was thus titled the 12th baronet.
