It lies south of the Western Scheldt that separates the region from the remainder of Zeeland and the Netherlands to the north.
The region is bordered by the Zwin nature reserve in the West and the Drowned Land of Saeftinghe in the East.
Since local government boundary reforms in 2003, Zeelandic Flanders has consisted of only three municipalities: Sluis in the west, Terneuzen in the centre and Hulst in the east.
The region was on the front line in the Eighty Years' War and was conquered by the Dutch Republic in 1604.
Another famous occasion was shortly after World War I. Belgium once again claimed both Zeelandic Flanders and Limburg, this time as a reconciliation.
In the central regions, the Land-van-Axels and Land-van-Cadzands dialects of Zeelandic, itself a transition language between West Flemish and Hollandic, are spoken.
