Aselin Debison (b. June 27, 1990) is a Canadian celtic pop singer.

Born in Cape Breton, Nova Scotia as the daughter of a hairdresser and a landscaper, she was named after Aslan, the lion in C. S. Lewis's Chronicles of Narnia. She began her singing career in 1999, when she was asked to sing at a rally of protesting miners in her hometown. In 2002, she was spotted by Sony Classical president Peter Gelb at the East Coast Music Awards. Her debut album Sweet is the Melody appeared that same year.
