St. Michael und St. Gertraud, Roman Catholic church in Neustadt am Main, Germany.

St. Michael und St. Gertraud Neustadt am Main is a Catholic church built as a three-nave basilica topped with two towers, with a north tower from the 11th century standing separately from the main structure. The building displays Neo-Romanesque style with carefully designed interior furnishings and serves as a landmark in the town center.

The church was rebuilt after lightning destroyed its predecessor in 1857 and was consecrated in December 1879 in Neo-Romanesque style. The north tower, however, dates from an earlier period and survived the disaster, making it a direct link to the site's medieval origins.

The parish is part of the Pfarreiengemeinschaft 12 Apostel am Tor zum Spessart, a union of 15 churches including those in Lohr, Pflochsbach and Sendelbach. The church's double patronage of Michael and Gertraud replaced the earlier dedication to Maria and Martin at the 1879 consecration. In the former chapter house, now the weekday church, hang the coat of arms of Abbot Bernhard Krieg and portraits of seven abbots.

The church stands beside the Main and a bridge, with its west entrance facing the river; the former monastery entrance is still marked by columns and a threshold in the northwest side-aisle wall. The floor has risen over 2 m since the 12th century, so the bases of the older piers now lie hidden beneath the present ground.

Above the former chapter house, now used as a weekday church, parish priest Rudolf Langhans set up a small museum called a lapidarium, though it holds more than stone. On display are pieces from the Carolingian and Romanesque building, among them braided stones, the fragment of a portal column and a reconstructed section of cloister with original capitals and small columns.
