Pedro Armengol (c. 1238 - 27 April 1304), born Pedro Armengol Rocafort, was a Spanish Roman Catholic who was of noble stock and was a thief during his adolescence. He became a professed member of the Mercedarians after he experienced a sudden conversion and devoted himself from liberating persecuted Christians from the Moors. Armengol is best known for being hanged while a captive of the Moors but survived the attempted killing. He received canonization as a saint on 8 April 1687 after Pope Innocent XI approved his sainthood and his long-standing "cultus" - or devotion.
