Archmere Academy is a private Catholic college preparatory school in Claymont, Delaware, United States.

[4] Archmere Academy began slowly expanding during the mid to late 1930s due to enrollment increases.

In 1957, Archmere Academy celebrated its 25th anniversary with the groundbreaking for St. Norbert Hall, the school's main academic building, which was completed in 1959.

In April 2001, an internal dispute among the Norbertines relating to the establishment of Claymont Priory separate from Daylesford Abbey spilled over into the administration of Archmere Academy.

Interventions from alumni calmed the turmoil and resulted in the academy taking control of the former Raskob residence, known as "the Patio.

The school broke tradition with the installation of a non-Norbertine headmaster when Dr. Michael Marinelli, a 1976 graduate of Archmere Academy, took over at the beginning of 2010.

[11] Towards the end of the 2015–16 academic school year, Archmere began massive renovations on Saint Norbert's Hall.

The Patio, one of the buildings of Archmere Academy, was built between 1916 and 1918 and was originally used as the country estate of John J. Raskob and his wife.

Raskob was a financier, the developer of the Empire State Building, and a previous chairman for the Democratic National Committee.

[13] Archmere competes in the Diamond State Conference for interscholastic sports such as American football, field hockey, basketball, rugby, soccer, swimming, diving, lacrosse, volleyball, golf, tennis, cheerleading, baseball, softball, cross country, track and field and wrestling.

[citation needed] Archmere has won a number of DIAA championships, such as cross country, volleyball and rugby.

The rugby team would win again in 2019, capturing the Mark Dombroski Cup and the Subaru 7's Regional Championship.

[16] In the 2022 Field Hockey season, Archmere's Varsity team advanced to the DII State Championship for the first time in 23 years.
