Antonio Posateri SJ (30 April 1640 – 18 January 1705), also known as Zhang Jingzhai, was a Jesuit missionary in Qing China. He arrived in China in 1676 and worked in regions such as Guangdong, Shanghai, Nanjing, Shaanxi and Gansu. In 1696, he became the first ever apostolic vicar in Shanxi and was well on his way to become a bishop. Unfortunately, he would never become one as he died in 1705.
