Angelus of Jerusalem, OCarm (Italian: Sant'Angelo; 1185 – 5 May 1220) was a Catholic convert from Judaism and a religious priest of the Carmelites of the Ancient Observance.

Unlike his brother, however, he retreated into the desert to a hermitage after his ordination, but he emerged once he was instructed to go to the Italian mainland to evangelize as well as to meet with Pope Honorius III to have him approve a new rule for the Carmelites.

His parents died while Angelus and his brother were still children, and the Patriarch Nicodemus oversaw their education until the twins turned eighteen.

Miraculous cures were attributed to him around this time and his "acta" stated that he sought to avoid fame and withdrew to a hermitage in the desert when he was becoming popular for his miracles.

In 1632 his relics were translated to the Carmelite Church,[4] and are now housed at the Santuario della Madonna del Carmine in Catania; the ending of a plague in the Kingdom of Naples in 1656, was attributed to his intercession.

[3] As he and Albert of Trapani were the first two saints in the Order to have a cult, they are frequently found in medieval Carmelite iconography alongside the Virgin Mary.

[6] In the Carmelite church of Santa Maria del Carmelo in Traspontina in Rome, there is a chapel dedicated to St. Angelus with an altarpiece by Giovanni Battista Ricci.
