St. Marien, Lutheran parish church in Weigenheim, Germany.

St. Marien is a hall church built between 1491 and 1511 in Reusch, a district of Weigenheim. Its plastered nave was rebuilt after a collapse in 1700/01, and a four-storey choir flank tower of ashlar masonry stands on the north wall of the choir. The tower's upper storey and its eight-sided slate-clad spire were renewed in 1948.

The nave and choir were built between 1491 and 1511; the nave collapsed and was rebuilt in 1700/01. The four-storey choir flank tower on the north wall received its renewed upper storey and eight-sided slate-clad helm in 1948. In the 18th century a hexagonal timber-framed stair tower with a bell-shaped hood was added to the north side of the nave.
