Kamenice river () is a tributary of the Jizera river in the Czech Republic. It rises from several source streams in the Jizera Mountains () of Bohemia at Holubník (the pigeon-house) (1070 m). Below the former crystal production village of Kristiánov (Christiansthal), a locality in the Bedřichov (Friedrichswald), only Liščí bouda (Fuchsbaude) remains preserved as a glass museum near where the Kamenice meets the Josefův Důl dam. The Josefův Důl dam, above the village Josefův Důl, was built between 1976 and 1982 and is the largest dam in the Jizera Mountains. It has a height of 43 m and a capacity of 23 million cubic meters. It is used for drinking water, so recreational activities are not permitted upon it.
