The Penobscot River (Abenaki: Pαnawάhpskewtəkʷ) is a 109-mile-long (175 km) river in the U.S. state of Maine. Including the river's West Branch and South Branch increases the Penobscot's length to 264 miles (425 km), making it the second-longest river system in Maine and the longest entirely in the state. Its drainage basin contains 8,610 square miles (22,300 km2).

It arises from four branches in several lakes in north-central Maine, which flow generally east. After the uniting of the West Branch with the East Branch at Medway (45°36′14″N 68°31′52″W / 45.604°N 68.531°W / 45.604; -68.531 (Penobscot River source)), the Penobscot flows 109 miles (175 km) south, past the city of Bangor, where it becomes navigable. Also at Bangor is the tributary Kenduskeag Stream. It empties into the Atlantic Ocean in Penobscot Bay. It is home to the Penobscot people that live on Indian Island, and considered to be The People's lifeblood.
