De Moer is one of the three church villages of the Dutch municipality of Loon op Zand. De Moer, on January 1, 2008, contained 538 inhabitants.
De Moer is nowadays largely in an agricultural development on former farmland. To the east the ground is higher and sandier. Here is the estate Huis ter Heide with dry woods (coniferous trees and American oak) and friends. This estate is bordered by the northeast of the Loon and Drunen Dunes and in the north of the Loeland.
