The United States Interstate Highway System is a network of highways that connects cities and regions across the United States. The system was authorized by the Federal Aid Highway Act of 1956, and construction began in the late 1950s. The highways are numbered and designated with the prefix "I-", followed by a number that indicates its location and direction.

As of 2022, there are 70 primary and auxiliary Interstate highways in the United States, with a total length of over 48,000 miles (77,000 km). The longest of these is I-90, which spans over 3,000 miles (4,800 km) from Seattle, Washington to Boston, Massachusetts. The shortest is I-878, located in New York City, with a length of just 0.7 miles (1.1 km).
