The Little Sisters of the Assumption is a Roman Catholic religious institute founded in France in 1865 by Antoinette Fage (1824–1883) and Etienne Pernet. The declared work of the congregation is the nursing of the sick poor in their own homes. This labour they perform gratuitously and without distinction of creed.

The Assumptionists, formally known as the Congregation of the Augustinians of the Assumption, is a worldwide congregation of Catholic priests and brothers. It is active in many countries. The French branch played a major role in French political and social history in the 19th century.
