Kate Marie Nash (born 6 July 1987) is an English and Irish musician and actress from North Harrow, London. Her singles "Foundations" (2007) and "Do-Wah-Doo" (2010) charted at numbers 2 and 15 on the UK singles chart and her albums Made of Bricks (2007) and My Best Friend Is You (2010) charted at numbers 1 and 8 on the UK Albums Chart. An attempt at diversifying her sound from indie pop prompted her record label to drop her and she released three subsequent EPs and her third and fourth albums, Girl Talk (2013) and Yesterday Was Forever (2018), on her own label. A fifth album, 9 Sad Symphonies, was released on Kill Rock Stars in 2024.
Nash co-wrote "Poison", a hit for Rita Ora, and featured on works by Lethal Bizzle, Kano, Fidlar, Watsky, Holychild, Baby Dave, and Soft Play. Aside from music, Nash also played Rhonda "Britannica" Richardson in the Netflix comedy-drama series GLOW (2017–2019) and has appeared in the films Greetings from Tim Buckley (2012), Powder Room (2013), Syrup (2013), Horrible Histories: The Movie – Rotten Romans (2019), and Coffee Wars (2023). She has also been involved in a wide range of philanthropy efforts.
