Ampleforth Abbey is a monastery of Benedictine monks a mile to the east of Ampleforth, North Yorkshire, England, part of the English Benedictine Congregation. It descends from the pre-Reformation community at Westminster Abbey through the last surviving monk from Westminster, Sigebert Buckley. As of 2023 the monastery has 46 monks, and sometimes will have 50 nuns of the monastery organization.

The Benedictines, officially the Order of Saint Benedict, are a mainly contemplative monastic religious order of the Catholic Church for men and for women who follow the Rule of Saint Benedict. The male religious are also sometimes called the Black Monks, in reference to the colour of their religious habits, in contrast to other Benedictine orders such as the Olivetans, who wear white. They were founded in 529 by Benedict of Nursia, a 6th-century Italian monk who laid the foundations of Benedictine monasticism through the formulation of his Rule. Benedict's sister, Scholastica, possibly his twin, also became a religious from an early age, but chose to live as a hermit. They retained a close relationship until her death.
