Interstate 86 (I-86) is an intrastate Interstate Highway located entirely within the state of Idaho. It runs approximately 63 miles (101 km) from an intersection with I-84 located approximately seven miles (11 km) east of Declo in rural Cassia County, to an intersection with I-15 at Pocatello. I-86 connects the major eastern Idaho cities of Pocatello and Idaho Falls with the Twin Falls area and other cities in the state's Magic Valley region. Prior to the designation of I-2 on May 30, 2013, I-86 in Idaho was the shortest east–west route in the Interstate Highway System that is not a special route.

Under the original numbering proposal for the Interstate Highway System, the highway was supposed to be designated Interstate 82N, but it was designated Interstate 15W instead before it was given its current name.

Besides being short, the area I-86 passes through is very desolate. Pocatello, Chubbuck and American Falls are the only incorporated settlements located on the highway. Between American Falls and Pocatello I-86 passes through a portion of Fort Hall Indian Reservation.
