Sluis (Dutch: [slœys] ⓘ; Zeelandic: Sluus [slys]; French: Écluse) is a city and municipality located in the west of Zeelandic Flanders, in the south-western Dutch province of Zeeland.
The current incarnation of the municipality has existed since 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 in 1995.
