János Brenner

János Brenner, O.Cist (; religious name: Anasztáz Brenner; 27 December 1931 – 15 December 1957) was a Hungarian Catholic priest and member of the Cistercian Order. Brenner studied for the priesthood during a period of communist persecution of religious orders. Communist authorities came to suspect him of being critical of their regime; his success as a youth chaplain made him a threat. As a consequence, he was murdered by hired men who stabbed him 32 times and inflicted severe wounds to his head using canes. He died soon after having been hurled into a ditch in the woods. The beatification took place on 1 May 2018 in Szombathely.

Life János Brenner was born on 27 December 1931 in the Vas province as the second of three boys. His two brothers also became priests.

He attended a Cistercian-run grammar school in Pécs from 1941 to 1946 after the Brenners moved there. He later attended the grammar school that the Premonstratensian Canons ran and graduated from the Cistercian school in Zirc. Brenner is commemorated, along with Blessed Maria Sagheddu, in an altarpiece at Heiligenkreuz Abbey in Austria.
