Dendermonde (French: Termonde) is a Belgian city and municipality located in the Flemish province of East Flanders in the Denderstreek. The municipality comprises the city of Dendermonde proper and the towns of Appels, Baasrode, Grembergen, Mespelare, Oudegem, Schoonaarde, and Sint-Gillis-bij-Dendermonde. As its name implies, Dendermonde is located at the mouth of the river Dender, where it flows into the Scheldt.

The current Mayor of Dendermonde is Piet Buyse (Christian Democratic and Flemish).

Some interesting La-Tène artifacts were found in Appels, proof that this region of the Scheldt was inhabited in prehistory. Grave sites from the 2nd and 6th century also attest to dense settlement in Gallo-Roman and Merovingian times. In 843, the Treaty of Verdun placed Dendermonde in Lotharingia. After the Norman invasions of 883, however, Baldwin II took over the region and incorporated it into the German part of the newly founded County of Flanders.

Otto II built a fort here in the 10th century, encouraging further settlements in the area. The town received its city charter in 1233 and grew quickly after that thanks to a thriving cloth industry. Several cloisters, chapels and churches, and a fortified defensive wall were built as well. A cloth hall and belfry were erected on the market square in the mid 14th century. The town’s prosperity, however, gave rise to severe competition with cities such as Ghent and to occasional attacks and plunders by neighbours. In 1384, the whole area came under the control of the Valois Dukes of Burgundy
