The Birch Creek is a 241 km long left tributary of the Yukon River in the Interior of Alaska .

It rises in the Steese National Conservation Area in the Tanana Hills north of Chena Hot Springs on the Steese Highway , flows first for a few kilometers in a south and then in an easterly direction, then turns north and runs parallel to the Yukon River, into which it finally flows west flows from Fort Yukon . The estuary is in the Yukon Flats National Wildlife Refuge .

The Birch Creek splits into two estuary arms. The north running Upper Mouth Birch Creek flows 40 km southwest of Fort Yukon into the Yukon River. The Lower Mouth Birch Creek flows south and flows 62 km southwest of Fort Yukon into the Lower Birch Creek Slough , a southern branch of the Yukon River.

The river was named in the mid-19th century by merchants from the Hudson's Bay Company from Fort Yukon. The name of the natives for the upper reaches is "Tohwun-nukakat". An expedition of the Western Union Telegraph Company reported in 1867 of the name "Nocotocargut", which probably refers to the estuary.

In 1891 gold was found in Birch Creek.

The upper reaches of Birch Creek was designated as a National Wild and Scenic River under the administration of the Bureau of Land Management in 1980 by the Alaska National Interest Lands Conservation Act .
