Pfarrkirche Großmeiseldorf, Gemeinde Ziersdorf, Roman Catholic church in Ziersdorf, Austria

Pfarrkirche Großmeiseldorf is a late-Baroque hall church built in 1780–1786, standing on elevated ground north of the village in the market town of Ziersdorf, Lower Austria. A south-facing facade tower with a clock and onion dome projects between the gable slopes; the rounded choir is surrounded by a cemetery.

Construction of the church began in 1780; it was consecrated in 1783 and structurally completed in 1786. That same year the parish was founded and incorporated into Melk Abbey. The building is a late-Baroque hall church with a south facade tower and a cemetery around the choir.

The parish was founded in 1783 and incorporated into Melk Abbey, which supplied furnishings from dissolved monastery churches. The high altar (c. 1720/1730) holds Martin Grassinger's Trinity painting of 1802, flanked by carved plague saints Sebastian and Rochus from the first half of the 18th century, once placed above the former offering portals.

The church stands on the northern shoulder of the terrain, raised above Großmeiseldorf, with the cemetery around the choir; the south tower faces the village. The interior is reached from the south front. The site lies in the market municipality of Ziersdorf, Hollabrunn district, Lower Austria.

The organ was built by Franz Josef Swoboda in 1909, not in 2010. Much of the interior furnishings were reused from dissolved monastery churches, so the altars and statues did not originally belong to this church.
