Flobecq (French: [flɔbɛk] ⓘ; Dutch: Vloesberg [ˈvluzbɛr(ə)x]; Picard: Flôbek) is a municipality of Wallonia located in the province of Hainaut, Belgium.

Each year, on the nearest Friday to 17 January, there is a marvelous local feast based on the adoration of Saint Antony.

Therefore, the region (including neighbouring places like Lessines, Ellezelles, ...) was often called "debate land" (Dutch: debattenland; French: terre des débats).

In 1963, when the language border was fixed, within the municipality of Flobecq, only the village of La Houppe/D'Hoppe was Dutch-speaking.

However, the village was not transferred to Dutch-speaking East Flanders and remained in French-speaking area.
