Monte Cassino Girls High School is a Catholic boarding-school in the Mashonaland East province of Zimbabwe.
It was built between two mountain ranges, with its entrance coming in from the west side after crossing the Mucheke River, 7 km south-east of Macheke.
A day and boarding school for boys was opened in 1908 and the following year, the monks formed the Missionary Order of Mariannhill.
In 1996, Ampleforth monks from the English Benedictine Congregation arrived at the mission and established the Monastery of Christ the Word.
In 2017, it was ranked as one of the top ten boarding schools in Zimbabwe, based on O-level and A-level results.
