Havré (French pronunciation: [avʁe]; Walloon: Avrè) is a sub-municipality of the city of Mons located in the province of Hainaut, Wallonia, Belgium.
It is situated next to Boussoit, Bray, Mons, Obourg, Saint-Symphorien, Ville-sur-Haine, and Villers-Saint-Ghislain.
Havré was a wealthy municipality from the 19th century to 1950, with forests, salt refinery, tannery, tabac fabric, gunpowder factory, glass factory, phosphate quarry, but mostly thanks to coal mines which employed more than a thousand people.
In 1960, after the last coal mine closed, the village became a commuter-town for people mainly working in Brussels, Mons, and Charleroi.
In the tertiary sector of the economy, Havré counts small and medium supermarkets, and there are retail and handicraft shops.
