The Blackthorn is an Irish whiskey or sloe gin based cocktail. Both versions emerged in the late 19th and early 20th century.

While these two version are the dominant ones today, there were several variations that early 20th century bartenders would have been aware of. Bill Boothby's World Drinks and How to Mix Them (1934) includes five different "Blackthorn" cocktails.
