Saint María Josefa Sancho de Guerra (7 September 1842 – 20 March 1912) was a Spanish Roman Catholic nun who established her own congregation known as the Servants of Jesus of Charity.
She wanted her new congregation to focus on the care of the sick and the poor.
She assumed the name of "María Josefa of the Heart of Jesus".
Pope John Paul II beatified her on 27 September 1992 and canonized her on 1 October 2000.
