Whiskey in the Jar is an Irish traditional song set in the southern mountains of Ireland, often with specific mention of counties Cork and Kerry. The song, about a rapparee (highwayman) who is betrayed by his wife or lover, is one of the most widely performed traditional Irish songs and has been recorded by numerous artists since the 1950s.
The song's exact origins are unknown. A number of its lines and the general plot resemble those of a contemporary broadside ballad "Patrick Fleming" (also called "Patrick Flemmen he was a Valiant Soldier") about Irish highwayman Patrick Fleming, who was executed in 1650.
