Delone Catholic High School is a regional high school named for Charles J. Delone, Esquire, a prominent Catholic attorney of Hanover, Pennsylvania, who donated the land and the funds for the construction of the original building. The facilities that had been the education center for the elementary and high school had been destroyed by a fire in 1938, which precipitated Delone's donation. The cornerstone of the new school was laid in 1939, and the new building was dedicated by Archbishop Amleto Giovanni Cicognani, Apostolic Delegate to the United States, on September 2, 1940. As a tribute to Delone, the school bears his name and its athletic teams have adopted his title: "Squires" and "Squirettes".
Father Cyril J. Allwein was appointed the first principal. The Sisters of Saint Joseph were joined on the faculty by the Sisters of Mercy and, in 1941, by the Sisters of Christian Charity.
In 1952, the high school was accredited by the Middle States Association under the direction of Father William R. Lyons, Principal 1948-1977. Two wings were added to the original building in 1955 and 1962. A chapel bearing the title "Our Lady, Queen of Peace" was constructed in 1966. The Lawrence B. (Sonny) Sheppard Memorial, a gymnasium complex, the gift of Mr. and Mrs. L.B. Sheppard in memory of their son, was built in 1968.
Delone Catholic exhibits one of the first Freedom Shrines, donated by the Hanover Exchange Club and dedicated on March 26, 1957. The shrine displays a variety of documents, including the U.S. Declaration of Independence, the Gettysburg Address and the treaties of World War II.[2] A rededication ceremony was held on September 16, 2009. Joe Dittmar, a survivor of the September 11, 2001, attack on the World Trade Centers, gave the keynote address.

James "Jimmy" Smith won the PCIAA State Wrestling Championship in the unlimited weight class in 1972, before Catholic high schools could compete in PIAA competition. Tom Koontz won the same PCIAA State Title in 1974. His brother, Tony Koontz, won the PIAA Class AA Wrestling State Championship in the unlimited weight class in both 1983 and 1984. Dana Gingrich won the 2003 State Championship in the 130 lb. weight class. In 2010, Tyler Small won the PIAA Class AA Wrestling State Championship in the 125 lb. weight class.[10]
The football team's annual game against the cross-town rival Hanover High School is Pennsylvania's third-longest prep football series. The Squires now have a 43-28-5 lead in the 75-year-old rivalry with Delone taking 24 of the last 30[when?] meetings.
Delone Catholic's 2009 track and field team was the first track team to win a District Championship. They received the trophy on May 16, 2009.
