Nederweert (Dutch: [ˈneːdərˌʋeːrt] ⓘ; Limburgish: Ni-jwieërt [ˈnɪjˌwiəʀt]) is a municipality and a town in southeastern Netherlands with a population of 17,171 as of 2021 and has an area of 101.78 km2 (39.30 sq mi) of which 1.80 km2 (0.69 sq mi) is water.

Nederweert lies at the intersection of three channels: the Zuid-Willemsvaart, the Noordervaart and the Wessem-Nederweert Canal.

In the 19th century these channels provided transport routes to export peat that was harvested from the Peel.

Nederweert was originally called 'Merefelt' which means 'amongst the lakes', though it was later named Weert van den nedersten eynde.

During this era it was part of the Belgian departement of the Nedermaas.
