Maryknoll School is a private, coeducational Catholic school serving children in kindergarten through twelfth grade in Honolulu, Hawaiʻi. The school is located on the island of Oʻahu and is administered by the Diocese of Honolulu in association with its original founders, the Maryknoll Society of brothers and priests and the Maryknoll Congregation also called the Maryknoll Sisters. The school is the largest Catholic School in the state of Hawaii, and the fifth largest private school in the state. Maryknoll has developed 6 sister schools and 5 affiliated school connections, in China, Japan, and Vietnam.

The school started out as a one-story wood-frame building containing four classrooms. It was blessed and dedicated in 1927 and opened with a student body of 93 boys and 77 girls in the lower grade levels. The six Maryknoll Sisters, who had arrived from New York just four days before opening day, comprised the first faculty.

In 1931, the Maryknoll Sisters expanded the school to accommodate older students; in 1935, Maryknoll School graduated its first class. As of the 2017 - 2018 school year, Maryknoll School has a student body of nearly 1,100 students.^[2]
