Rosary Convent High School is a Roman Catholic private-run girls' school in Hyderabad, India. Established in 1904 by the Franciscan Missionaries of Mary, it continues to be run by these Missionary Sisters who reside in their convent at the school's grounds. The school was established in response to a need for Catholic girls' education. It became the sister school to All Saints High School, the area's prime Catholic boys' school in those days. These two schools are located on either side of St Joseph's Cathedral in Gunfoundry, Hyderabad, India.
