New York State Route 417 (NY 417) is an east–west state highway located in the Southern Tier of New York in the United States. It begins at exit 20 of the Southern Tier Expressway (Interstate 86 or I-86 and NY 17) in the city of Salamanca and ends at a junction with NY 415 in Painted Post, west of the city of Corning. At 105.25 miles (169.38 km) in length, NY 417 is the longest of the state highways that were formerly part of NY 17 before the construction of the Southern Tier Expressway. It also diverges the most from the current NY 17, coming within 100 feet (30 m) of the Pennsylvania state line at one intersection.

In 1908, the New York State Legislature created Route 4, an unsigned legislative route extending across the Southern Tier from Lake Erie to the Hudson River. The route followed most of what is now NY 417; however, from Olean to Wellsville and from Andover to Jasper, it followed a more northerly alignment instead. Most of Route 4 became NY 17 in 1924, and NY 17 was realigned in 1930 to follow all of modern NY 417 between Salamanca and Corning. The highway remained part of NY 17 until the 1960s and 1970s, when NY 17 was moved onto the Southern Tier Expressway as sections of the new freeway opened to traffic.
