Lucy Caroline Halliday (born 2003) is a Scottish actress. She rose to prominence in 2022 after making her screen debut in the British drama Blue Jean, for which she received a British Independent Film Award nomination and won the BAFTA Scotland Award for Best Actress.
She appeared in the musical biographical film California Schemin' (2025) alongside James McAvoy, before taking the co-lead role of Daisy in The Testaments (2026).
Early life and career Halliday was born and raised in Paisley where she took part in youth theatre productions with PACE Youth Theatre from a young age. Despite her early involvement in acting, she did not initially consider it a long-term career and had set those ambitions aside by the time she reached adulthood. After being accepted to study medicine, her plans changed when Halliday came across an open casting call for Blue Jean and decided to audition.
Blue Jean was Halliday's first professional audition. By her own account, she did not match the brief listed in the call, but emailed the production regardless. She was cast as Lois, a secondary school student. At the 2022 British Independent Film Awards, Halliday was nominated for Best Supporting Performance, and was also included in the ensemble nomination shared by the cast. She won the Actress Film award at the BAFTA Scotland Awards in Glasgow on 19 November 2023 for her debut screen performance.
In 2025, Halliday appeared as Mary Boyd in California Schemin', a musical biographical film based on Gavin Bain's memoir of the same name. The film tells the true story of Silibil N' Brains, a rap duo from Dundee. Halliday was listed among the principal cast alongside Séamus McLean Ross and Samuel Bottomley.
Halliday stars in Hulu's television adaptation of Margaret Atwood's 2019 novel The Testaments, a sequel to The Handmaid's Tale. She portrays Daisy, one of the two protagonists.
Halliday is set to star as Ann Westbourne in the upcoming drama film 7 Miles Out, which is scheduled to be released by Cannon and Morley Productions and Revolution Films.
