St. Vicenta María López y Vicuña (†1890) was a Spanish professed religious and the founder of the Religious of Mary Immaculate. Her order was dedicated to administering to "working girls", or young women in domestic employment, and she took the view that these housemaids and other domestic servants needed care, with a particular emphasis on girls who suffered abuse. Pope Pius XII presided over her beatification in 1950 and Pope Paul VI later proclaimed her to be a saint in 1975. Her Feast Day is celebrated on 26 December.
