Saint Jaime Hilario Barbal (2 January 1898 – 18 January 1937) – born Manuel Barbal i Cosín – was a Catalan Roman Catholic and a professed religious brother from the Institute of the Brothers of the Christian Schools.
He served for almost two decades as a teacher in the schools that his order managed until being caught up in the turmoil of the Spanish Civil War that saw the forces of the Second Spanish Republic execute him.His beatification was celebrated on 29 April 1990 after it was confirmed that Barbal was killed "in odium fidei" ("in hatred of the faith") and the confirmation of a miracle attributed to his intercession allowed for Pope John Paul II to canonize him as a saint of the Roman Catholic Church on 21 November 1999.
