Hofkirche, Court church in Neuburg an der Donau, Germany

The Hofkirche Mariä Himmelfahrt is a Catholic church on Karlsplatz in Neuburg an der Donau, built from 1607/08 as a Protestant court church after designs by Josef Heintz and Sigmund Doctor, modelled on St. Michael in Munich. Its yellow west facade and tower were completed in 1624 by Johann Alberthal and Antonio Serro; the tower carries a clock, a belfry and a green copper dome. The interior holds stucco work of 1616–1619 by Gian Antonio and Pietro Castelli and a 1968 Offner organ with 38 stops and over 2,500 pipes.

A palace chapel dedicated to St. Mary stood on this site over 1,000 years ago; under Duke Heinrich IV a Benedictine convent followed, and after the Protestant Reformation the tower collapsed in 1585. The present church was begun in 1607/08 to plans by court painter Josef Heintz and court architect Sigmund Doctor, modeled on Munich's Jesuit church St. Michael. Prince Wolfgang Wilhelm converted it to a Catholic Jesuit church in 1613, and Johann Alberthal and Antonio Serro completed the west facade and tower in 1624.

The church is dedicated to the Assumption of Mary, but its interior follows the Counter-Reformation programme set after 1613: the high altarpiece was Rubens's Great Last Judgment, completed in 1617 and now in Munich's Alte Pinakothek. The side altars, also by Rubens, were taken to Düsseldorf in 1703 and are now in the Staatsgalerie in Neuburg Castle. The stucco work of 1616–1619 is by Gian Antonio and Pietro Castelli of Melide.

The Hofkirche stands on Karlsplatz, its west facade and tower facing the square; a connecting passage links it to the castle. The interior is entered from the square side, with the nave and side altars laid out around the high altar. The organ, built by Maximilian Offner in 1968, has 38 stops on three manuals and pedal and over 2,500 pipes, revised in 2023.

Two crypts lie beneath the church: a smaller one holding seven members of the Wittelsbach family and a larger one containing the remains of roughly fifty Jesuit fathers. These hidden chambers tell of the place's significance for two separate communities.
