Under the direction of the Archdiocese of Baltimore, the school was founded in 1963 as a parish high school for girls, and was originally staffed by the Sisters of Notre Dame de Namur. Known at the time as Holy Trinity High School, the school relocated to the present campus in 1966.

Upon moving to New Cut Road, His Eminence Lawrence Cardinal Sheehan renamed the school Martin Spalding High School in honor of the seventh Archbishop of Baltimore. With foresight that the local residential area would continue to grow and see more families recognizing the value of a Catholic education, in 1973 the school became co-educational, welcoming the first boys as freshmen and sophomores. Growth continued throughout the 1980’s as the school began to offer new academic courses and an expanded athletic program. In 1986, the school changed its formal name to Archbishop Spalding High School and by the end of the decade the school’s enrollment topped 1,000 students.  Today, we welcome students from more than 60 middle schools in 8 counties.
