The Dithmarscher Eiderwatt, officially the Dithmarscher Eidervorland mit Watt, is a nature reserve in the districts of Dithmarschen and Nordfriesland in the north German state of Schleswig-Holstein. The site has an area of 620 hectares which consists of the mudflats on the tidal current of the river Eider.
The nature reserve is mainly located on the Dithmarschen side of the Eider foreland, from the Eider Barrage to the Eider bridge on the B 5 federal highway near Tönning. It lies within the municipal boundaries of the villages of Wesselburenerkoog and Karolinenkoog, and partly in Tönning. On the North Frisian side of the river lies the Katinger Watt area.
