Pfarrkirche Groß-Jedlersdorf, Catholic church in Floridsdorf, Austria.

Pfarrkirche Groß-Jedlersdorf is a single-nave Catholic church standing free on Amtsstraße in Vienna's 21st district, where it narrows the street to one lane. It has a slightly projecting main room, a lower rectangular choir to the south, a trapezoidal entrance bay with gabled facade, and an asymmetrically placed tower with a Welsh bonnet roof. The walls are pierced by rectangular and segmental-arched windows, and the hipped roof is covered in beaver-tail tiles.

Jedlersdorf was its own parish from 1538 to 1583, then belonged to Kagran. After the plague of 1713–1714, the 37 survivors built a wooden chapel, enlarged until 1764. In 1748 a fire destroyed the village; the Marian image Klein-Maria-Taferl was thrown into the flames and found intact, drawing pilgrims. Joseph II approved the parish in 1783, dedicated to Charles Borromeo; the church was enlarged with a tower in 1785, damaged in 1809 at Wagram and restored by 1822.

The church is also known as the Wallfahrtskirche Klein-Maria-Taferl, after a small crowned Pietà print, only 15 by 20 cm, that was thrown into the flames during the 1748 fire and found intact. Pilgrims came to pray before this Flammen-Madonna. The high altar, with adoring angels, dates from the mid-19th century.

The church stands on the sidewalk of the main street in the former village of Jedlersdorf, where it narrows Amtsstraße to a single lane. It is an active parish church, so visitors should avoid times of services and community events. The building is a protected monument.

The high altar image is a small printed crowned Pietà, only 15 by 20 cm, known as the Flammen-Madonna. According to legend it was thrown into the flames during the 1748 fire that devastated Jedlersdorf and was later found unharmed under charred rubble, which made the church a pilgrimage site.
