New York State Route 812 (NY 812) is a state highway in the North Country of New York in the United States. The southern terminus of the route is at an intersection with NY 12 and NY 26 in the Lewis County village of Lowville. Its northern terminus is at the Canada–United States border in Ogdensburg, where it crosses the Ogdensburg–Prescott International Bridge and connects to Highway 16 in Ontario. While most of NY 812 passes through rural areas of the North Country, the route also serves several villages and small communities. The GPS services company Geotab has named it the quietest highway in New York due to its low traffic counts.^[3]

The origins of NY 812 date back to the 1930 renumbering of state highways in New York, when the portion of modern NY 812 from Lowville to Croghan became part of NY 26A and the segment of modern NY 812 between De Kalb and Ogdensburg was designated as the northernmost portion of New York State Route 87. NY 87 originally extended as far south as Harrisville; however, it was truncated north to Edwards in the 1940s and farther north to De Kalb in the 1970s.

On July 1, 1977, all of NY 87 and the Lowville–Croghan leg of NY 26A were replaced with NY 812, a new route that began in Lowville and passed through Croghan, Harrisville, Gouverneur, and De Kalb before ending near Ogdensburg. At the time, two sections of the route—from the Croghan village line to a point west of Harrisville and from Harrisville to Fowler—were maintained by the counties that they passed through, and a piece between NY 126 and the Croghan village line was maintained by the village itself. The state of New York assumed maintenance of the Croghan–Harrisville segment in 1980 and took over the Harrisville–Fowler section in 1982.
