Antonius of Weert was a 16th-century Franciscan friar and Catholic priest from Weert. During the Dutch Revolt, he was a member of the Convent of Gorcum. He was arrested by Calvinists along with eighteen other men, including eleven of his fellow Franciscans. These individuals were eventually executed on July 9, 1572, in Brielle, making him one of the eighteen men remembered as the Martyrs of Gorkum.
