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.

NY 9R begins opposite the entrance to the on-ramp for Interstate 87 (I-87) exit 7 at an intersection with US 9 (Loudon Road) in the Colonie hamlet of Latham, located north of the city of Albany. The junction is also the termination of the off-ramp from the limited-access NY 7 west onto US 9. NY 9R heads east as the four-lane Columbia Street Extension, initially passing through a commercialized area centered around the route's intersections with US 9 and the nearby Old Loudon Road. The commercial strip ends at Johnson Road, where the route turns northeastward and narrows to two lanes as it heads into a lightly populated area of Colonie. This section of Columbia Street Extension passes by some commercial buildings; however, most of the development along the highway is residential, with most of the homes located in cul-de-sacs leading away from NY 9R.
