Armengol de Aspa (died after April 1191), also known as Hermangard d'Asp, was the ninth Grand Master of the Knights Hospitaller, holding the office from 1188 until his resignation in 1189 or 1190.[1] He succeeded William Borrel who was interim Grand Master. It was under his magistracy that the headquarters of the Order was transferred from Jerusalem to Tyre.[2] It was probably during the winter of 1189 or 1190 that Armengol's magistracy ceased, but this was not due to his death, since he appears again as lord of Amposta from December 1190 to April 1191. We have no information on what this first abdication in the history of the Order was, but he was succeeded by Garnier de Nablus sometime in 1190.[3]
