Sulz im Weinviertel is a town in the district of Gänserndorf in the Austrian state of Lower Austria.

The blue and red in the coat of arms signify the lords of Liechtenstein, who originally occupied part of the area under the lordship of Wilfersdorf.

The golden grapes on the left of the coat are based on the agricultural history of the area, which comprised a lot of the economy in antiquity.

The silve oath hand on the right side of the coat point symbolically to the Heiligenkreuz Abbey, which has been active since the 12th century.

The coat of arms was dedicated on 7 June 1980 by Governor of Lower Austria, Andreas Maurer.
