Astrik was a 10th and 11th-century Benedictine monk and preeminent religious leader in the early Kingdom of Hungary. Originally from the Duchy of Bavaria, he served as the first abbot of the Pannonhalma Archabbey and later became the first archbishop of Esztergom. He played a crucial role in the diplomatic relations between King Stephen I and Pope Sylvester II, eventually participating in the coronation of the Hungarian king in 1001.
