The Shawangunk Kill is a 47.2-mile-long (76.0 km)[1] stream that flows northward through Orange, Sullivan and Ulster counties, New York, in the United States.

From its source in Greenville, the Shawangunk flows steadily northeastward to Mill Pond, near Mount Hope, by which point it has already lost almost half its original elevation.

Several miles to the north, the confluence of another tributary, the Platte Kill, marks the point where Orange, Sullivan and Ulster counties come together as the stream bends slightly towards a more eastern heading.

Fish and Wildlife Service, when it was researching the fate of the former Galeville air base site (now Shawangunk Grasslands National Wildlife Refuge) found that the lower Shawangunk (from its mouth to Pine Bush) supports an unusually diverse plant and animal community for the region due to the absence of any serious impoundment along the upper river.

[2] In 2015 the town council members of Wallkill, through which five miles (8.0 km) of the stream flows, enacted a law to protect the Shawangunk Kill.
