Neustadt am Main Abbey was an abbey of the Benedictine Order in Neustadt am Main, Bavaria, Germany. It existed from the 8th century until the dissolution of abbeys in the course of secularization in 1803. During its heyday in the early Middle Ages, the abbey was a political power that vied for regional influence with the Prince-bishops of Würzburg, the Archbishops of Mainz and the Counts of Rieneck. Today its location is occupied by a monastery operated by the nuns of the "Dominican Order of Saint Catherine of Siena", also known as Kloster Neustadt. The former abbey church today serves as the Catholic parish church for Neustadt.
