William Dunbar (1459 or 1460 – by 1530) was a Scottish makar, or court poet, active in the late fifteenth and early sixteenth centuries. He was closely associated with the court of King James IV and produced a large body of work in Scots distinguished by its great variation in themes and literary styles. He was probably a native of East Lothian, as assumed from a satirical reference in The Flyting of Dumbar and Kennedie. His surname is also spelt Dumbar.
Dunbar first appears in the historical record in 1474 as a new student or determinant of the Faculty of Arts at the University of St Andrews. Since the customary age for entering a Scottish university at this time was fourteen, a birth-date of 1459 or 1460 has been assumed. At St Andrews, he obtained a bachelor's degree in 1477 and a master's degree in 1479. Details from his later life suggest that he was ordained as a priest at some point, but the date is unknown.
