Marymount Primary School (Chinese: 瑪利曼小學) is a Catholic primary school located on Tai Hang Road, Happy Valley, Hong Kong Island, Hong Kong.
In October 1957, the school moved to its present location on the wooded slopes at the top of Blue Pool Road, overlooking Happy Valley.
The sponsorship of the school was transferred by the Columban Sisters to the Christian Life Community in 1998.
Marymount Primary School moved back to Tai Hang Road in September 2006.
Certain few exceptions were made for a small number of boys at grades Kindergarten through form 2 only in Maryknoll Sisters Primary School.
