Eckartsau (Czech: [[Krcov]]) is a town in the district of Gänserndorf in the Austrian state of Lower Austria.
Schloss Eckartsau was the last residence of Charles I of Austria prior to his departure from the former Austria-Hungary in March, 1919.
The present Eckartsau was formed in 1971 from the union of the market town Eckartsau with Witzelsdorf and the villages Kopfstetten, Pframa and Wagram.
