Temse (Dutch pronunciation: [ˈtɛmsə] ⓘ; French: Tamise [tamiz]) is a municipality in East Flanders, Belgium.

The main sights include the Church of Our Lady, whose steeple was designed by the famous sculptor Adriaan Nijs, who died in Temse, and who also sculpted the wooden pulpit.

Close by stands the old "Gemeentehuis" (town hall), built in Flemish Eclectic style, housing a carillon in its main tower.

Temse is first mentioned under the name Temsica[2] in a deed from 941 in which Count Arnulf I of Flanders returns a series of possessions to St. Peter's Abbey in Ghent that his predecessors had taken.

[5] Like other places that were already known across the language border in the Middle Ages, Temse has a French name that has undergone its own sound development.

In a deed from 1221 in which Viscount Zeger III of Ghent renounces a few tithes in favor of the Bishop of Tournai, Temse is mentioned as Thamisia,[7] a name that will become Tamise in contemporary French.

Note that in the French variant of the name the suffix -(i)acum is missing, as is also the case with Geldenaken (from *Geldoniacum) and Jodoigne (from *Geldonia).

They had been active for the espionage service codenamed Theo, whose purpose was to inform the Belgian army about the movements of the German troops.
