New York State Route 203 (NY 203) is a state highway in the Capital District of New York in the United States. It begins at an intersection with NY 22 in the Columbia County hamlet of Austerlitz and ends at a junction with U.S. Route 20 (US 20) in the Rensselaer County village of Nassau. NY 203 was assigned as part of the 1930 renumbering of state highways in New York. Prior to that time, the section of NY 203 east of Valatie was part of NY 22. The road runs northwest-southeast, and is signed east-west east of Valatie and north-south north of Valatie.
