We are St. Mary's School of Piscataway, a Catholic elementary school serving prekindergarten through 8th grades. St. Mary’s promotes the spiritual, intellectual, physical, social, and emotional development of each child.

Our campus is nestled on more than 14 acres on the banks of the Piscataway Creek in beautiful Clinton, Maryland, in southern Prince George's County. We are located between Clinton, Fort Washington, Accokeek, and Waldorf.

In Christ’s Love,
