Ursula Ledóchowska, Polish-Austrian nun and saint, founded the Congregation of the Ursulines of the Agonizing Heart of Jesus (died 1939)

Julia Ledóchowska, USAHJ, religious name Maria Ursula of Jesus, was a Polish Catholic religious sister and the foundress of the Ursulines of the Agonizing Heart of Jesus. Ledóchowska was a prolific supporter of Polish independence which she often spoke about at conferences across Scandinavia while she settled in Russia for a time to open convents until her expulsion. But she continued to found convents across Scandinavian countries and even translated a Finnish catechism for the faithful there while later founding her own order which she would later manage from Rome at the behest of Pope Benedict XV.

The Congregation of the Ursulines of the Agonizing Heart of Jesus, also known as the Grey Ursulines, is a Catholic religious institute founded by Ursula Ledóchowska in Poland. At present the congregation consists of over 900 sisters in 14 countries. The sisters are committed to the service of poor people and specialize in providing educational opportunities.
