St. Marienkirche, Catholic parish church in Wilmersdorf, Germany.

St. Marienkirche is a Catholic parish church in Charlottenburg-Wilmersdorf featuring an oval floor plan built in red brick. The interior follows a cross-shaped layout beneath a central dome, with the altar area refreshed through renovations completed in 1990.

A fundraising drive from 1908 funded the first Catholic church in Wilmersdorf. The foundation stone was laid on 20 April 1913 to designs by Christoph Hehl and Carl Kühn, and the church was blessed on 11 October 1914. War and inflation delayed consecration until 15 November 1925. It became a parish in 1921 and was merged into Maria unter dem Kreuz in 2009.

The parish has run a soup kitchen in the church rooms since November 1993, serving around 50 to 70 homeless and low-income people daily. Volunteers from all six deanery parishes hand out food and hot drinks, and showers, a washing machine, a clothes bank and medical care are also provided. Meals are delivered by cooks from St. Dominicus.

Sunday Mass is celebrated at 9:30 and 11:00, with an anticipated Sunday Mass on Saturday at 18:30. The church stands on Bergheimer Platz right at the boundary with Friedenau. Since November 1993 the parish has provided rooms for a soup kitchen run by the Wilmersdorf deanery, serving about 50 to 70 people daily, with showers, a washing machine, a clothes bank and medical care.

The organ, built in 1925 by Anton Feith senior, keeps about 70% of its original pipes, the largest surviving Feith instrument. Most pipes stand in two swell chambers inside the tower. Joseph Ahrens, organist here from 1929 to 1933, composed early organ works during these years.
