New York State Route 474 (NY 474) is a state highway located entirely within Chautauqua County in the westernmost corner of New York in the United States. It begins at the section of the Pennsylvania state line that runs north–south and runs eastward, initially paralleling the state line before taking a more northeasterly alignment toward Chautauqua Lake. The route ends adjacent to the lake at a junction with NY 394 in the town of Busti. NY 474 was originally designated as New York State Route 74 in 1930 before being renumbered to NY 474 on July 1, 1972. The route continues westward into Pennsylvania as Pennsylvania Route 474 (PA 474), which was assigned in the 1980s.

Chautauqua County is the westernmost county in the U.S. state of New York. As of the 2020 census, the population was 127,657. Its county seat is Mayville, and its largest city is Jamestown. Its name is believed to be the lone surviving remnant of the Erie language, a tongue lost in the 17th century Beaver Wars; its meaning is unknown and a subject of speculation. The county was created in 1808 and organized in 1811. The county is part of the Western New York region of the state.
