Elizabeth Davidson Fraser (born 29 August 1963) is a Scottish singer. She was the vocalist for the band Cocteau Twins who achieved success in the UK primarily during the fifteen years from the mid-1980s to the late 1990s. Their studio albums Victorialand (1986) and Heaven or Las Vegas (1990) both reached the top ten of the UK Album Charts, as well as other albums including Blue Bell Knoll (1988), Four-Calendar Café (1993) and Milk & Kisses (1996) charting on the Billboard 200 album charts in the United States as well as the top 20 in the UK. She also performed as part of the 4AD group This Mortal Coil, including the successful 1983 single "Song to the Siren", and as a guest with Massive Attack on their 1998 hit single "Teardrop".

When the Cocteau Twins disbanded, Fraser embarked on a moderately low-key solo career and provided guest vocals for other artists. She released some solo material, including singles "Underwater" (2000) and "Moses" (2009). Fraser has reportedly recorded enough material for a debut solo studio album; however, a release date or further information has not been published. In 2022, Fraser released the EP Sun's Signature, which includes a re-worked version of her 2000 single release "Underwater". In May 2022, Fraser and former band mates Robin Guthrie and Simon Raymonde were awarded the Visionary Award by The Ivors Academy.

Her distinctive style has received much critical praise in her four-decade career; She was described by critic Jason Ankeny as "an utterly unique performer whose swooping, operatic vocals relied less on any recognizable language than on the subjective sounds and textures of verbalized emotions".
