Schermer (Dutch pronunciation: [ˈsxɛrmər] ⓘ) is a former municipality in the Netherlands, in the province of North Holland.

Because of peat-digging and storm floods, this small river had by 1250 developed into an inland lake with an open connection with the Zuyderzee.

In 1635, 47.7 km2 (18.4 sq mi) of polder was drained, whereupon the land was divided among the shareholders.

In 1970, the village of Zuid- en Noord-Schermer was merged into Schermer.

[5] The municipality of Schermer included the following small towns and villages: Driehuizen, Grootschermer, Oterleek, Schermerhorn, Stompetoren, Zuidschermer.
