New York State Route 343 (also known as NY 343) is a state highway located entirely within central Dutchess County, in the Hudson Valley region of the U.S. state of New York. It runs east–west from the intersection of NY 82 in the village of Millbrook to the Connecticut state line in the town of Amenia, where it continues eastward briefly as Connecticut Route 343. Along the way, it has a 7.3-mile (11.7 km) concurrency with NY 22 from vicinity of the hamlet of Dover Plains to the hamlet of Amenia.

The entirety of modern Route 343 was originally the Dover branch of the Dutchess Turnpike. The turnpike, which was in operation from the early to the mid-nineteenth century, was a major transportation route at the time, connecting several local communities to Litchfield County, Connecticut, and the city of Poughkeepsie. NY 343 was designated in 1930, connecting the hamlet of Amenia to the state line, but was relocated a few years later onto the portion of New York State Route 200 from South Millbrook to the hamlet of Dover Plains. The NY 200 designation was then transferred to NY 343's original alignment.
