Manuel Ignacio Santa Cruz Loidi (1842–1926) was a Spanish Roman Catholic priest.
For some 35 years he served on apostolic mission in Colombia, where he was heading a parish in rural interior of the Pasto province; for some 15 years he held also various minor posts in Jamaica.
He is best known, however, for his activity in 1872-1873, when he commanded a Carlist guerilla unit during the civil war in Spain.
As "cura Santa Cruz" (priest Santa Cruz) or simply as "El Cura" (The Priest) he gained notoriety for cruelty and in the Spanish public discourse of the late 19th century he became a symbol of savage brutality.
In this role – though also with a grade of ambiguity - he featured as a protagonist in a few great works of Spanish Modernist literature of the early 20th century and became a mythical figure long before his own death.
