Stadtpfarrkirche St. Marien, Gothic parish church in Müncheberg, Germany.

Stadtpfarrkirche St. Marien is a parish church in Müncheberg featuring a neo-Gothic tower designed by Karl Friedrich Schinkel and an elongated rectangular choir from the 13th century. The building combines its historical walls with modern interior structures and now serves multiple functions as a community space.

Dendrochronology dates the fieldstone core to 1268±10 years. In the early 15th century the church was raised in brick, given buttresses and rebuilt as a two-aisle hall with star vaults on two octagonal piers. After structural damage the west tower was demolished in 1817–1827 and rebuilt four metres from the nave to a design by Karl Friedrich Schinkel. On 19 April 1945 shelling set the church alight; roof, vaults and piers collapsed, only the outer walls and largely intact tower remained. The roof was restored 1991–1996.

The church is also known as Pfarrkirche St. Marien and is an open church, kept unlocked for visitors. Its name links it to the town's main parish. Since the 1990s rebuild it has served as church, library and event venue, and a bell cast in 1621 survives from the earlier furnishings.

The church is an open church, so the interior can normally be visited outside service times. The west tower stands four metres apart from the nave, linked to the roof by a bridge-like passage over a pointed arch; the tower itself is not described as climbable. North and south portals with porches give access.

During reconstruction, a modern structure called 'Die Arche' was inserted inside, creating multiple functional levels without destroying the historical walls. This innovative solution shows how tradition and contemporary design coexist within the same space.
