Muiden (Dutch pronunciation: [ˈmœydə(n)] ⓘ) is a city and former municipality in the Netherlands, in the province of North Holland.

The first known reference to Muiden is from 953 when Otto I, Holy Roman Emperor, granted the settlement and its toll rights to the Cathedral of Saint Martin, Utrecht.

Developments in warfare during the Franco-Prussian War of 1870 prompted modernisation, with the construction of forts, part of the Stelling van Amsterdam, which included the Muizenfort, the barracks on the Vestingplein, and the casemates in the ravelins.

Together with the lighthouse island near Durgerdam and the artillery battery at the Diemer seawall, it was meant to protect the entrance of the IJ Bay and the harbour of Amsterdam.

Explosions since 1883:[3] Marleen de Pater-van der Meer of the Christian Democratic Appeal (CDA) was the last mayor of Muiden.
