The Tumtum River is a 9-mile (14 km) tributary of the Marys River in Benton and Lincoln counties in the U.S. state of Oregon.

The name Tumtum is a Chinook Jargon word for "heart", and the river was so-named because it was considered to be the heart of the valley through which it flowed. When the Burnt Woods post office was to be named, one of the names proposed to the Post Office Department was Tumtum.
