Kirche Jesu Christi der Heiligen der Letzten Tage in Wien, Mormon church in Gregorygasse, Vienna, Austria.

The Church of Jesus Christ of Latter-day Saints in Vienna comprises four meeting houses; the oldest, at Böcklinstraße 55 in Leopoldstadt, was built from 1960 to 1963 to plans by architect Werner Schröfl. Its assembly hall holds a Walcker organ, and the building houses the Vienna stake centre and a publicly accessible genealogy research centre. The Silbergasse house in Döbling, built around 1975, is a white-painted concrete building whose baptismal room has light-blue mosaic.

Two missionaries from Idaho arrived in Vienna in 1949, and the church gained state recognition in Austria in 1955. The Leopoldstadt congregation first sought an existing house to convert, then bought the Böcklinstraße plot and built a new meetinghouse from 1960 to 1963 to plans by architect Werner Schröfl. It was dedicated on 5 November 1961 during a visit by President Henry D. Moyle, before construction was finished.

The Böcklinstraße building houses the stake centre of the Vienna stake, comparable to a diocese, and is the meeting house of the Wien-Leopoldstadt congregation. A genealogy research centre open to the public is also housed here. The Silbergasse building serves the Wien-Döbling congregation, whose meetings are held in English.

The four meetinghouses are spread across Vienna: Böcklinstraße 55 in Leopoldstadt, Silbergasse in Döbling, Gregorygasse 29 in Liesing and Elfingerweg 2A at the city border with Gerasdorf. The Böcklinstraße building holds the stake centre and a genealogy research centre open to the public. Services in Döbling are held in English.

The Walcker organ stands in the assembly hall of the Böcklinstraße 55 meetinghouse in Leopoldstadt, the church's first building in Vienna, consecrated on 5 November 1961 during a visit by President Henry D. Moyle while construction was still unfinished. The same house holds the Vienna stake centre and a genealogy research centre open to the public.
