The Felician Sisters, in full Congregation of Sisters of St. Felix of Cantalice Third Order Regular of St. Francis of Assisi, is a religious institute of pontifical right whose members profess public vows of and live in common. This religious institute was founded in Warsaw, Poland, in 1855, by Angela Truszkowska, and named for a shrine of Saint Felix of Cantalice, a 16th-century Capuchin especially devoted to children.

Felix of Cantalice, OFMCap was an Italian Capuchin friar of the 16th century. Canonized by Pope Clement XI in 1712, he was the first Capuchin friar to be named a saint. He worked as a shepherd and farmhand until he was twenty-eight. His task as a Capuchin was to beg alms for the friars. So successful was he that Brother Felix was able to extend his collections to assist the poor.
