The island of Manhattan is surrounded by which three rivers?

The iconic shape of Manhattan is defined by three distinct bodies of water that officially make it an island. To the west flows the mighty Hudson River, a massive waterway that separates Manhattan from the state of New Jersey. On the eastern side is the East River, which is technically not a river at all. It's a saltwater (Deals) tidal strait, a channel connecting New York Bay to the Long Island Sound. Finally, completing the circuit to the north is the Harlem River, which flows between the Hudson and East Rivers, separating the borough of Manhattan from the Bronx.

This unique geography was fundamental to the city's development. Long before bridges and tunnels, these waterways were the primary highways for trade and transportation, turning the port of New York into a global economic powerhouse. The name "Manhattan" itself is derived from the Lenape word "Manna-hatta," often translated as "island of many hills," a direct acknowledgment of the landscape shaped by these surrounding waters. Together, these three waterways—a major river, a tidal strait, and a connecting channel—create the geographic boundaries of one of the world's most famous islands.
