Archbishop Chapelle High School was founded in 1962 by the Archdiocese of New Orleans and was named after Archbishop Placide Louis Chapelle, the first Archbishop of New Orleans in the twentieth century. The Sisters of Charity of the Incarnate Word staffed the school. In the first year, there were 236 students with nine teachers, which included four religious and four lay teachers. An additional grade was added each year thereafter until the 1965–1966 school year, which also saw Chapelle's first graduating class.
