New York State Route 9R (NY 9R) is a north–south state highway in northeastern Albany County, New York, in the United States. The route is a 3.22-mile (5.18 km) eastern loop of U.S. Route 9 (US 9), connecting that route to the city of Cohoes 1.5 miles (2.4 km) to the east. It leaves US 9 in the hamlet of Latham and rejoins its parent in the hamlet of Boght Corners, both located in the town of Colonie. Most of NY 9R is a two-lane highway that passes through residential areas; however, the southwesternmost portion of the route is four lanes wide and serves a commercial district. The route was assigned c. 1939 and has remained largely unchanged since that time, save for a brief period during the 1970s where NY 9R was partially replaced by NY 470.
