St. Peter und Paul, Lutheran church in Reutlingen, Germany

St. Peter und Paul is a Lutheran church in Reutlingen featuring Neo-Gothic design with a simple rectangular structure. A prominent tower rises above the city and forms part of the skyline visible from many parts of town.

Grave slabs and cemetery remains point to a church here before the 12th century, when a Romanesque apse church was built, its foundations found beneath today's choir. In the 13th century a defensive three-storey stone tower rose on the south side, the oldest surviving part. Around 1400 the rectangular choir was replaced by a Gothic one. In 1842–44 Johann Georg Rupp built the Neo-Gothic hall church, as a 1827 parish report noted the old church was too cramped for the schoolchildren and adults.

The church bears the names of the apostles Peter and Paul and belongs to the Gönningen parish within the Reutlingen church district of the Evangelical Lutheran Church in Württemberg. The building is listed as a monument by the Baden-Württemberg State Office for Monument Preservation.

The church stands in Gönningen, a district south of Reutlingen's centre, so it is reached by road rather than on foot from the town. The oldest surviving part is the 13th-century tower on the south side of the Gothic choir; the 1842–44 nave by Johann Georg Rupp extends west of it. The building is a registered monument.

The organ, built in 1844 by Franz Xaver Engelfried of Horb, was reconstructed by the Rensch firm in 1970 using good documentation, largely returning it to its original state; it has 24 stops on two manuals and pedal with mechanical action. A cleaning and tuning followed in 2005.
