Linge is a river in the Betuwe that is over 100 km long, which makes it one of the longest rivers that flow entirely within the Netherlands.

It starts near the village Doornenburg near the German border. It flows to Zoelen, a small village north of Tiel and from there on meanders through the Betuwe, to end in the Boven Merwede near Gorinchem. Until Geldermalsen the river is little more than a small, canalised stream. From Geldermalsen on however, it begins to look like a real river complete with dikes and small floodplains. The river was once a branch of the river Waal, being cut off at Tiel in 1307 or thereabouts (some traces of this can still be seen). The river is navigable for small vessels and is a popular destination for boaters. The banks of the river are important breeding grounds for waterfowl.

This river used to be an important trade route in old days. This role has nowadays been taken by the Rhine and Waal rivers.

The riverbanks in the Betuwe are lined with apple orchards, which make it popular with tourists particulary in spring the fruit trees are in blossom, In April, a walking-tour is organised in support of the Red Cross, the so called 'Rode Kruis Bloesemtocht'.
