The Delta River is a 130 km long river in Alaska. It rises in the south central Alaska from the Tangle Lakes, a group of lakes on the Denali Highway, flows northward through the Alaska Range into the Interior and flows into the Tanana River Big Delta.
Through the Alaska Range and the Tanana Valley of the Richardson Highway runs parallel to the Delta River.
The upper reaches of the Delta River from the Tangle Lakes to the Black Rapids in 1980 reported by the Alaska National Interest Lands Conservation Act as a National Wild and Scenic River under the administration of the Bureau of Land Management.
