Comines-Warneton (French: [kɔmin waʁnətɔ̃] ⓘ; Dutch: Komen-Waasten [ˈkoːmə(ɱ) ˈʋaːstə(n)] ⓘ; Picard: Comène-Warneuton; West Flemish: Koomn-Woastn; Walloon: Cômene-Varneton) is a city and municipality of Wallonia located in the province of Hainaut, Belgium.

It is contiguous with the identically named Comines on the other side of the border with France.

[citation needed] Comines-Warneton is a municipality with language facilities for Dutch-speakers.

The municipality consists of the following districts: Bas-Warneton, Comines, Houthem, Ploegsteert, and Warneton (including the hamlet of Gheer).

Since then, the municipality forms an exclave of both Hainaut and Wallonia, being surrounded by the Flemish province of West Flanders and the French department of Nord and not connected to the rest of the French-speaking area of Belgium.
