The area was formerly controlled by the Onondaga people. French missionaries and explorers passed through the area in the middle of the 17th century.
The town of Cape Vincent was originally part of the town of Lyme. In 1849 the town of Cape Vincent separated from Lyme. The village of Cape Vincent was incorporated in 1853. At the time of its incorporation the village had a population of 1,218.
By the end of the 19th century, the area was becoming a vacation land due to the nearby Thousand Islands.
According to the United States Census Bureau, Cape Vincent has a total area of 0.73 square miles (1.9 km2), of which 0.02 square miles (0.06 km2), or 3.31%, are water.[2] The village is on the south bank of the St. Lawrence River. A seasonal ferry connects the village to Point Alexandria on Wolfe Island in Ontario, Canada, 1 mile (1.6 km) from Cape Vincent across the southern channel of the St. Lawrence.
New York State Route 12E passes through the village center, leading northeast (downstream) along the St. Lawrence 15 miles (24 km) to Clayton and southeast 25 miles (40 km) to Watertown, the Jefferson county seat.
As of the census[6] of 2000, there were 760 people, 348 households, and 209 families residing in the village. There is one local bank (Citizens' Bank of Cape Vincent), a small museum, a post office (ZIP 13618), an independent telephone exchange and a few small stores.

The privately owned Horne's Ferry, the only international ferry in the region, runs from May to October to Cape Vincent from "Horne's Point" (Point Alexandria) on Wolfe Island, Ontario, Canada, in the Thousand Islands. The capacity is about twelve cars. The family-owned ferry has been running since 1802 when they were first licensed to operate between Wolfe Island and Cape Vincent (as well as Wolfe Island and Kingston, Ontario). The cost as of 2013[update] was US$15 for one car and driver.
Another ferry on the opposite side of Wolfe Island runs year-round free of charge and completed the crossing between Marysville and Kingston. The total time for both ferry crossings was a little over an hour.
Beginning in April 1852, the Cape Vincent branch of the Rome, Watertown & Ogdensburg Railroad (RW&O) conveyed both passengers and freight between the waterfront and Watertown (and on to Rome) via Chaumont and Brownville. The Watertown-Cape Vincent branch was a vital link from the southern part of the state to the ferry terminal to Canada. However, its importance was reduced with the company's acquisition of the Utica & Black River Railroad (with its depot in Clayton) in 1886. By 1891 the railroad became a subsidiary of the New York Central Railroad. In 1895, a storm blew down the Cape Vincent station building, killing two inside.
From the early part of the 20th century onward, traffic decreased until the New York Central ended its passenger service to the village in March 1936, after which, Clayton, to the east, became the main launch point for rail to ferry connections. Freight operations closed in the early 1950s. The second and final station building, having served its original purpose for over 40 years, still stands on the waterfront; it now functions as the offices of Anchor Marina.
