The Susitna River (soo-SIT-nuh) is a river, approximately 300 mi (480 km) long, in south central Alaska in the United States. It provides the primary drainage for a broad valley, called the Susitna Valley, south of the Alaska Range, emptying Cook Inlet northwest of Anchorage.
It rises in the Susitna Glacier on Mt. Hayes in the Alaska Range near 63°30′N 147°15′W / 63.500°N 147.250°W / 63.500; -147.250. It flows in winding course generally southwest to Curry, then south, along the west side of the Talkeetna Mountains, past Talkeetna, Chulitna, and Susitna, to the head of Cook Inlet, approximately 25 mi (40 km) west of Anchorage.
It receives the Yentna River from the northwest approximately 5 mi (8 km) north of Susitna. It is navigable to 85 mi (137 km) upstream from its mouth to Talkeetna.
