The Susquehanna River, located in the northeastern United States, stretches for 444 miles from its source in upstate New York to the Chesapeake Bay. It has played a significant role in the history of the region, serving as a transportation route for Native Americans and early settlers. The river's hydrology is characterized by high flow variability, with floods and droughts being common. The river is home to several reservoirs and dams, including the Conowingo Dam and the Safe Harbor Dam, both of which generate hydroelectric power. Recreational activities such as fishing, boating, and camping are popular along the river, and it also supports agriculture by providing irrigation for crops. However, pollution from agricultural runoff and other sources has impacted the river's water quality and ecosystem.

The Susquehanna River (; Lenape: Siskëwahane) is a major river located in the northeastern and mid-Atlantic United States. At 444 miles (715 km) long, it is the longest river on the East Coast of the United States that drains into the Atlantic Ocean. With its watershed, it is the 16th-largest river in the United States, and the longest river in the early 21st-century continental United States without commercial boat traffic.
The Susquehanna River forms from two main branches: the "North Branch", which rises in Cooperstown, New York, and is regarded by federal mapmakers as the main branch or headwaters, and the West Branch, which rises in western Pennsylvania and joins the main branch near Northumberland in central Pennsylvania.
The river drains 27,500 square miles (71,000 km2), including nearly half of the land area of Pennsylvania. The drainage basin (watershed) includes portions of the Allegheny Plateau region of the Appalachian Mountains, cutting through a succession of water gaps in a broad zigzag course to flow across the rural heartland of southeastern Pennsylvania and northeastern Maryland in the lateral near-parallel array of mountain ridges. The river empties into the northern end of the Chesapeake Bay at Perryville and Havre de Grace, Maryland, providing half of the Bay's freshwater inflow. The Chesapeake Bay is the ria of the Susquehanna.
