St Mary's College, (known colloquially as Marys), is an Australian Catholic secondary school for girls, located in Ipswich, Queensland, Australia. The school accepts girl students from year 7 to year 12, drawing from a wide area of Ipswich, Queensland. The total enrolment is approximately 650. The school is a member of the Catholic Secondary Schoolgirls' Sports Association. St Mary's School was established by Sisters of Mercy in 1863 as part of St Mary's Parish for the parish's primary-aged children. In 1913, St Mary's College was established as a separate secondary school exclusively for the higher education of girls in the Mercy tradition. The College and its pupils were now distinct from the Primary School students. The Sisters of Mercy ceased administering and teaching at the school in the early 1990s. The college is owned by the Parish and is now administered and staffed by Brisbane Catholic Education.
