Kirche Neumargareten, Catholic church in Meidling district, Vienna, Austria.

Kirche Neumargareten is a hall church built 1949–1953 to plans by Helene Koller-Buchwieser and Hans Steineder at Flurschützstraße 1, on the Meidling side of the border with Margareten. A planned bell tower was never built. Inside, large wall and ceiling paintings by Hans Alexander Brunner show Mary Immaculate in a halo of rays surrounded by saints.

The building was completed in 1953 by architects Helene Koller-Buchwieser and Hans Steineder as part of Vienna's post-war reconstruction efforts. It represents the period when the city was developing new modern structures for its growing communities.

The parish name Neumargareten recalls the district border: the area belonged to Margareten before passing to Meidling. The church was deconsecrated in 2025, and the farewell Mass on 22 June 2025 was led by Cardinal Christoph Schönborn. A chapel keeps a Marian statue rescued from the first church, destroyed in 1944.

The church stands at Flurschützstraße 1, on the border between Meidling and Margareten, opposite the Haydnpark that was once the Hundsturmer cemetery. The building was deconsecrated in 2025, so no services are held; its future use is still under discussion. The 18th-century statue of St John Nepomuk stands in front of the church.

The organ on the rear gallery was built in 1955 by Gebrüder Mauracher of Linz, with three manuals, a pedal and 52 registers. It is the last large new organ completed by that firm before it closed, ending an Austrian organ-building dynasty.
