The Last Day (Welsh: Y Dydd Olaf) is a Welsh science fiction novel by Owain Owain, written in 1968 and first published in 1976. It was significantly revised and reprinted until the definitive version in 2021. It was also published in Cornish (2020), English (2024) and Polish (2025). It is one of the most famous novels in the Welsh language. In October 2014, the novel gave great influence to inspire singer Gwenno Saunders to compose and publish the music album with the same name; the album received critical acclaim and was chosen by Allmusic as one of the best Indie Records of 2015. London's Loud and Quiet called it the second best album of 2015.
