Sluis ( pronunciation ) is the name of both a municipality and a town located in the west of Zeelandic Flanders, in the south-western part of the Netherlands.

The current incarnation of the municipality exists since on 1 January 2003. The former municipalities of Oostburg and Sluis-Aardenburg merged on that date. The latter of these two municipalities was formed from a merger between the previous municipality named Sluis and the former municipality of Aardenburg.
