The following is a list of Interstate Highways in New York. There are currently 30 Interstate Highways—eight primary Interstates and 22 auxiliary Interstates—that exist entirely or partially in the U.S. state of New York. In New York, Interstate Highways are mostly maintained by the New York State Department of Transportation (NYSDOT), with some exceptions. Unlike in some other states, Interstate Highways in New York are not directly referenced by NYSDOT with their number; instead, the letter "I" is suffixed to the number of the route on reference markers and in internal documents. On the surface, there appears to be numerical duplication between Interstate Highways and state routes—such as Interstate 86 and New York State Route 86—but the "I" suffix that is appended to Interstate Highway numbers allows the Interstate Highway and state route to co-exist ("86I" versus "86", respectively).

There are a combined 1,674 mi (2,694 km) of Interstate Highways within New York, which handles about 19 percent of vehicle travel in New York.^[1] At approximately 0.50 mi (0.80 km), Interstate 78 is the shortest Primary Interstate, while Interstate 90 is the longest, spanning 385.88 mi (621.01 km) within New York. Interstate 878, located in Queens, is the shortest active Auxiliary Interstate Highway in the Interstate Highway System.

Small portions of Interstate 278 in New York City are maintained by local authorities rather than the state transportation agency.^[2] In addition, parts of Interstate 84, Interstate 87, Interstate 287, Interstate 90, Interstate 190, and Interstate 95 are part of the New York State Thruway system and thus are maintained by the New York State Thruway Authority.

Designations that are shaded in dark gray are numbers not currently assigned to a highway.
