Punahou School is a private, co-educational college preparatory school serving over 3,770 students from kindergarten through grade 12 in Honolulu, Hawaii. Founded in 1841 by Protestant missionaries as Oahu College, it occupies 76 acres of land originally granted by Kamehameha and is claimed to be the largest independent K–12 school on a single campus in the United States.
The school maintains institutional commitments to spiritual and ethical values, creativity, and cultural diversity. Its curriculum combines rigorous academics with extensive co-curricular offerings in arts, athletics, and global education. The institution emphasizes social responsibility, sustainability, and civic engagement alongside traditional college preparatory preparation.
With over 180 years of operation, Punahou draws on its Hawaiian and Christian heritage while serving a contemporary student population. The school's scale and breadth of offerings - spanning kindergarten through twelfth grade on a single campus - position it as a significant employer and educational institution in Hawaii.
