Northampton School for Girls (NSG) is a girls-only comprehensive secondary school with academy status, in Northampton, Northamptonshire, England. In 2004, the school gained specialist Music College status, the first school in England to do so. This resulted in a provision of musical opportunities for both students and the local community. It is also home to Spinney Hill Theatre, where both NSG students and other groups regularly perform. The theatre was used for classical music productions whilst work was undertaken on the Derngate theatre.
