Doworst is a humorous poem written by J.R.R. Tolkien.
The poem, written in a medieval style reminding of Piers Plowman, was a given by Tolkien to R.W. Chambers in December 1933. Eventually, the decorated manuscript containing the poem came into the possession of Arthur Brown, Professor of English at Monash University in Australia.
Two publications related to the Monash University have reproduced parts of the manuscript:
- 1975: Monash Review 3 (title of poem appearing as "Do Worst")
- 1978: A Elbereth Gilthoniel! 1, no. 2
