Delden is a city in the Dutch province of Overijssel and, since 2001, in the municipality of Hof van Twente. It received city rights in 1333. Twickel Castle is a famous landmark near Delden.

Before it became a part of Hof van Twente in 2001, Delden consisted of two municipalities: Stad Delden (the city itself), and Ambt Delden (the surrounding countryside). These municipalities had existed since 1818, when the original municipality "Delden" was divided into two parts.

The ground moraine was temporarily exposed here during the construction of the Twente canal in 1934-1935. Several pieces of amber were found.
