Somerville House is an independent, boarding and day school for girls, located in South Brisbane, an inner-city suburb of Brisbane, Queensland, Australia. Established in 1899 as The Brisbane High School for Girls, the School was eventually named after the Scottish scientific writer, Mary Somerville (1780–1872), though the school's official name is still Brisbane High School for Girls. Today, Somerville House is owned by the Presbyterian and Methodist Schools Association (PMSA), and provides classes from Preparatory to Year 12, within three sub-schools — Junior (Years Prep to 6), Middle (Years 7 to 9), and Senior (Years 10 to 12). The school currently caters for approximately 1,200 students from Prep to Year 12, including 97 boarders from Years 7 to 12.
