The John Llewellyn Rhys Prize is a literary prize awarded annually for the best work of literature (fiction, non-fiction, poetry, drama) by an author from the Commonwealth aged 35 or under, written in English and published in the United Kingdom. It is the second oldest literary award in the UK.
Since 2011 the award has been suspended due to funding problems. The last award was in 2010.
The prize was initiated in 1942 by Jane Oliver in memory of her husband John Llewellyn Rhys, a young author who was killed on 5 August 1940 while serving as a bomberpilot in the Royal Air Force.
From 1987 to 2003, the prize was funded by the Mail on Sunday. The newspaper withdrew in 2003, after the 2002 prize was awarded to Mary Laven. Subsequently, the prize was sponsored by Booktrust, an independent educational charity, but in June 2011 the award was suspended by due to funding problems.  Booktrust said that it "strongly" intended to bring the award "back with a bang as soon as possible" as it looked for outside funding sources.
In 2010, the winner received £5,000, while the runners-up each received £500.
