The Dan (Hebrew: דן, romanized: Dan; Arabic: اللدان, romanized: Leddan) is a tributary of the Jordan River.

[4] The tribe of Dan conquered the city, named Laish at the time, which was then occupied by Canaanites.

Although the Dan River itself is only about 20 km (12 miles) long, its flow provides up to 238 million cubic meters of water annually to the Hulah Valley.

In 1966, this was a cause of dispute between Israeli water planners and conservationists, with the latter prevailing after three years of court appeals and adjudication.

The result was a conservation project of about 120 acres (0.49 km2) at the source of the river called the Tel Dan Nature Reserve.
