St Augustine's Abbey or Ramsgate Abbey is a former Benedictine abbey in Ramsgate. It was built in 1860 by Augustus Pugin and is a Grade II listed building. It was the first Benedictine monastery to be built in England since the Reformation. In 2010, the monks moved to St Augustine's Abbey in Chilworth, Surrey. The site is now owned by the Vincentian Congregation from Kerala, India. The church of St Augustine, across the road from the abbey site, belongs to the Archdiocese of Southwark and is a shrine of St Augustine of Canterbury.

The Subiaco Cassinese Congregation is an international union of Benedictine houses within the Benedictine Confederation. It developed from the Subiaco Congregation, which was formed in 1867 through the initiative of Dom Pietro Casaretto, O.S.B., as a reform of the way of life of monasteries of the Cassinese Congregation, formed in 1408, toward a stricter contemplative observance, and received final approval in 1872 by Pope Pius IX. After discussions between the two congregations at the start of the 21st century, approval was given by Pope Benedict XVI in 2013 for the incorporation of the Cassinese Congregation into its offshoot, the Subiaco Congregation. The expanded congregation was given this new name.
