New York State Route 103 (NY 103) is a state highway in Schenectady County, New York, in the United States. It runs for just 0.50 miles (0.80 km) from an intersection with NY 5S in the hamlet of Rotterdam Junction to NY 5 in the town of Glenville. In between, the route crosses the Mohawk River at Erie Canal at Lock 9. When it was assigned in the early 1930s, it was the only crossing of the Mohawk River between Pattersonville and downtown Schenectady. It later became the only bridge between Amsterdam and Schenectady. Its regional importance declined following the completion of NY 890 near Schenectady in 1998. In late 2011, NY 103 was closed for three months to repair parts of the road damaged by Hurricane Irene and Tropical Storm Lee.

NY 103 begins at an intersection with NY 5S in Rotterdam Junction, a hamlet in the town of Rotterdam. The highway heads northward as the two-lane Bridge Street, serving a block of homes as it intersects Alexander Drive and Leonard Road. An intersection with Riverside Drive marks the end of the second block and the start of the third, where NY 103 passes the only bit of commercial activity along the highway. From here, the route leaves the hamlet and begins to rise as it crosses a steel truss bridge over the Mohawk River, here part of the Erie Canal. The last third of the span crosses Erie Canal Lock 9. On the north side of the river, the route serves Lock 9 State Park before terminating at an intersection with NY 5 in a rural part of the town of Glenville.
