New York State Route 17K (NY 17K) is an east–west state highway located within Orange County, New York, in the United States. It extends for 22.01 miles (35.42 km) from an intersection with NY 17 east of Bloomingburg to a junction with U.S. Route 9W (US 9W) midway across the city of Newburgh. The western terminus was where NY 17K originally connected to its parent route, NY 17; it now meets NY 17 a short distance to the east at an interchange with the Quickway. In Newburgh, NY 17K becomes Broadway and serves as the city's primary east–west street. The road can be divided into a half west of Montgomery, where it runs through relatively undeveloped land, and an eastern half where it closely parallels Interstate 84 (I-84) and serves much more populated areas.
