The Ramu River is a major river in northern Papua New Guinea. The headwaters of the river are formed in the Kratke Range from where it then travels about 640 km (398 mi) northwest to the Bismarck Sea.
Along the Ramu's course, it receives numerous tributaries from the Bismarck Range to the south and the Finisterre and Adelbert.
