Citarum (Sundanese: Walungan Citarum) is the longest and largest river in West Java, Indonesia It is also the third longest river in Java after Bengawan Solo and Brantas. It has an important role in the life of the people of West Java, as it supports agriculture, water supply, fishery, industry, sewerage, electricity, etc.

In Indonesian history the Citarum is linked with the 4th century Tarumanagara kingdom, as the kingdom and the river shared the same etymology, derived from the word "Tarum" (Sundanese for indigo plant). The earlier 4th century BCE prehistoric Buni clay pottery-making culture flourished near the river's mouth. Stone inscriptions, Chinese sources, and archaeological sites such as Batujaya and Cibuaya, suggest that the human habitation and civilization has flourished in and around the river estuaries and river valley as early as 4th century and even earlier.

There are three hydroelectric powerplant dams installed along the Citarum: Saguling, Cirata, and Ir. H. Djuanda (Jatiluhur), all supplying the electricity for the Bandung and Greater Jakarta areas. The waters from these dams are also used to irrigate vast rice paddies in Karawang and Bekasi area, making northern West Java lowlands as one of the most productive rice farming areas.
