Jacqueline "Jacqui" Abbott (born 10 November 1973, St Helens, Lancashire, England) is a singer who was the lead vocalist with the band The Beautiful South after 1994, following the departure of Briana Corrigan.

With Abbott, the band released several Top 10 singles. Amongst their most successful hits during her stint were: "Rotterdam", "Perfect 10", "Don't Marry Her" and "Dream a Little Dream of Me". Abbott was discovered by Paul Heaton, the Beautiful South's other lead singer, after she and a friend met him outside a night club. Heaton invited them to a party, where Abbot's friend encouraged her to sing. Heaton was impressed with her singing, and later invited her to audition to replace Corrigan.
