Parish church Baumgarten, Parish church in Penzing district, Vienna, Austria.

Parish church Baumgarten is a Romanesque Revival and Heimatstil basilica built by Moritz Otto Kuntschik at Gruschaplatz on Linzer Straße. Its north facade carries two closely set octagonal twin towers, and a triumphal-arch portico precedes the main portal. A lower choir adjoins the nave to the south.

A late-Gothic chapel dedicated to Saint Anne stood in Unterbaumgarten until it was destroyed in the Turkish sieges and rebuilt between 1753 and 1755; in 1784 it became a parish church under Josephinian reforms. For Emperor Franz Joseph I's 1898 jubilee the St. Anna church building association pushed for a new church, built 1906-1908 to plans by Moritz Otto Kuntschik; the old church was demolished in 1908. Restorations followed in 1925, 1948 and 1956-1960, and in 2003 the roof tiles were replaced and seat heating installed.

The church is dedicated to Saint Anne, and its name recalls the late-Gothic St. Anna chapel in Unterbaumgarten that was destroyed in the Turkish sieges and rebuilt in 1753–1755. The 1898 church building association St. Anna, founded for Emperor Franz Joseph I's fiftieth jubilee, pushed for the present new building. Since 1 July 2019 Baumgarten has belonged, with Oberbaumgarten, to the parish Heilige Mutter Teresa.

The church stands on Gruschaplatz, just off Linzer Strasse in Baumgarten, in Vienna's 14th district. The main entrance faces north, under a triumphal-arch portico between the two octagonal towers; the lower choir closes the south end. Access follows service times, so plan a visit around Mass.

The church holds official protection status as a Denkmalgeschütztes Objekt, placing it among Austria's officially recognized architectural monuments. This designation reflects its importance to the architectural heritage of the Penzing district.
