It is a part of the municipality of Zaltbommel, and lies about 8 km southwest of that city.

The smaller village of Nederhemert-Zuid, with only about 25 inhabitants, lies south of the Afgedamde Maas.

Neder (lower) has been added to distinguish from Ophemert (upper).

The southern part has become a river island in 1904 due to the construction of the Heusden Canal and the Bergse Maas.

[8] Since 1904, the southern part shares the river island with Bern, however they have remained separate villages.
