Petruskirche, Protestant parish church in Renningen, Germany

The Petruskirche is a Protestant parish church in Renningen, built in 1601 over a Romanesque predecessor. Its nave has a barrel vault that is no longer visible, and the Gothic lower tower is topped by an octagonal bell storey added in 1845 by city architect Albert Föhr in neo-Gothic style. The choir has a ribbed vault, and a sacristy was added in 1766.

The main structure dates from 1601, built on Romanesque foundations. A major expansion took place in 1878 under architect Christian Friedrich von Leins.

The church is dedicated to Saint Peter and belongs to the Protestant parish of Renningen in the Leonberg church district. Inside, a late Gothic crucifix and a 1721 epitaph for cavalry captain Joh. Christian Schauroth survive, and a war memorial stands on the south side.

The modernized interior has been updated through renovations over the decades, allowing the building to serve contemporary needs. Visitors should check access options before visiting, as historic church buildings sometimes have limited opening hours.

The 1967 organ by Orgelbau Friedrich Weigle has 23 registers, expanded to 27 in 2007 across two manuals and pedal. It replaced a 16-register Link organ of 1877, which had itself replaced the "Malmsheimer Orgel" installed in 1726.
