New York State Route 346 (NY 346) and Vermont Route 346 (VT 346) are short, adjoining state highways in the northeastern United States. Together, they extend for a combined 7.25 miles (11.67 km) through the towns of Petersburgh in Rensselaer County, New York, and Pownal in Bennington County, Vermont. The bi-state highway begins at an intersection with NY 22 in the hamlet of North Petersburgh and heads generally southeastward across the New York–Vermont state line to a junction with U.S. Route 7 (US 7) in the village of Pownal. Both NY 346 and VT 346 parallel the Hoosick River.

The Vermont portion of the highway was originally designated as Vermont Route 112 by 1926. The New York continuation was assigned NY 346 as part of the 1930 renumbering of state highways in New York, and VT 112 was renumbered to VT 346 in the late 1930s to match the designation on the New York side. VT 346, the longer of the two routes at 4.628 miles (7.448 km) in length, is currently the highest-numbered state highway in Vermont.
