The College of All Saints was an ecclesiastical college in Maidstone, Kent, England, founded in 1395 by Archbishop Courtenay. It was part of the establishment of the nearby Archbishop's Palace, but was closed in 1546. The College church was the neighbouring Church of All Saints. Following its closure, the College estate was sold. The buildings and land passed through the ownership of three aristocratic families, being farmed until the late 19th century. A number of the College's buildings survive and all are listed buildings. Additionally, the whole site of the College is protected as a scheduled monument.
