Gillian Lesley Gilbert (born 27 January 1961) is an English musician, keyboardist, guitarist and singer, best known as a member of New Order and a founding member of The Other Two.
Gilbert's family moved from her birthplace Manchester to the nearby market town of Macclesfield when she was young. In a 1987 New Order interview, Gilbert says that she disliked living in Cheshire as a teenager and wanted to live in Manchester.
In the late 1970s, Gilbert was in a punk band with three girls, The Inadequates, who happened to rehearse next to Joy Division (which included singer Ian Curtis, guitarist Bernard Sumner, bassist Peter Hook, and drummer Stephen Morris.) In a 1987 interview with Option, Gilbert reflected on the first time she became familiar with Joy Division: "[W]e didn't have a car and us three needed a lift home. So we asked them, and they said, 'Alright, but you have to buy one of our singles.' So we did and got it home and played it on this horrible record player. We'd known Stephen before. We thought, 'My god, this sounds horrible.'" Gilbert would later begin dating Morris.
