The Victoria River is a river in the bioregion of Victoria Bonaparte in the Northern Territory of Australia. It flows for 560 kilometres (350 mi) from its source south of the Judbarra / Gregory National Park to the Joseph Bonaparte Gulf in the Timor Sea.
Flowing for 560 kilometres from its source, south of the Judbarra / Gregory National Park, until it enters Joseph Bonaparte Gulf in the Timor Sea, the Victoria River is the longest singularly named permanent river in the Northern Territory. It is the second longest permanent river in the Northern Territory, as defined by international standards, the longest being the Katherine/Daly River.
Important wetlands are found in the lower reaches of the river with forming suitable habitat for waterfowl breeding colonies and roosting sites for migratory shorebirds. Large areas of rice-grass floodplain grasslands are also found along the river.
Part of the area adjoining the river mouth has been identified as the Legune (Joseph Bonaparte Bay) Important Bird Area because of its importance for waterbirds.
