Finn and Hengest is a study by J.R.R Tolkien, published posthumously in book form in 1982.

Finn and Hengest are two Anglo-Saxon heroes appearing in the Old English epic poem Beowulf and in the fragment of The fight at Finnsburg. Hengest and Horsa (the names meaning "stallion" and "horse") were also two brothers, leaders (possibly mythical) of the first Anglo-Saxon immigrants to Britain as mercenaries in the 5th century.
