Saint Rafaela Porras Ayllón (†1925) was a Spanish Roman Catholic professed religious who established the Handmaids of the Sacred Heart of Jesus in conjunction with her sister Dolores; upon becoming a nun she assumed the religious name of "Mary of the Sacred Heart of Jesus". She was a nun for most of her life and devoted herself to the management of the congregation and resided in Rome until her death after her resignation as the order's superior in 1893. The approval of two miracles attributed to her intercession allowed for Pope Pius XII to preside over her beatification in 1952 and the approval of a third miracle allowed for Pope Paul VI to canonize her as a saint of the Roman Catholic Church in 1977; she is the patron of her order and her Feastday is commemorated on May 18.
