Marist College North Shore (MCNS) (often shortened to Marist North Shore, occasionally known as Marist College North Sydney and sometimes simply referred to as Marist Brothers or Marist), is a systemic Roman Catholic, secondary day school for boys, located in North Sydney, New South Wales, Australia, a suburb on Sydney's Lower North Shore. Founded in 1888, Marist College North Shore is conducted by the Marist Brothers, based on the teachings of the order's founder, St. Marcellin Champagnat. The school is non-selective, and currently caters for approximately 600 students from Years 7 to 12 (12 to 18 years old). The college is administered by the Catholic Education Office for the Archdiocese of Sydney, and is affiliated with the Association of Marist Schools of Australia (AMSA), as well as the Metropolitan Catholic Colleges Sports Association (MCC). Marist Education began in North Sydney on 2 July 1888. Since then, the school now called Marist College North Shore has experienced significant changes and development. Initially, it was established as a small two-room school in Ridge Street; the current site of St. Mary’s Primary School.
