Alexandra Ashley Hughes (born 31 July 1985), known by her stage name Allie X, is a Canadian singer, songwriter, and visual artist. She began her career as an indie pop artist in Toronto in the mid-2000s, playing with local bands and recording several albums.

After relocating to Los Angeles in 2013, Hughes began working with producers Cirkut and Billboard and achieved success with her 2014 single, "Catch", which peaked at number 55 on the Canadian Hot 100 chart. The song rose to prominence after pop singer Katy Perry referred to it as her "spring jam" on social media.

Hughes released her debut extended play in 2015, CollXtion I, followed by her debut studio album CollXtion II in 2017, and Super Sunset in 2018. In 2019, she also released an analog version of Super Sunset. Her second and third studio albums, Cape God and Girl with No Face, were released in 2020 and 2024, respectively.
