De Otter (Dutch pronunciation: [də ˈʔɔtər]) is a paltrok mill in Amsterdam, Netherlands which has been restored to working order.

It is the only one left over from a group of sawmills built in the area between the Kostverlorenvaart canal and the Singelgracht.

The firm Van der Beyl expanded their property by acquiring several neighboring sawmills.

In 1925 the sails were removed after the wooden windshaft was torn but the rest of the mill remained standing.

However the location of the mill for catching the wind was already difficult in the buildup area of Amsterdam and it got worse by the construction of large apartment buildings close to the windmill.
