The Ilyushin Il-18 (Russian: Илью́шин Ил-18; NATO reporting name: Coot) is a large turboprop airliner that first flew in 1957 and became one of the best known and most durable Soviet aircraft of its era. The Il-18 was one of the world's principal airliners for several decades and was widely exported. Due to the aircraft's airframe durability, many examples achieved over 45,000 flight hours and the type remains operational in both military and (to a lesser extent) civilian capacities. The Il-18's successor was the long range Il-62 jet airliner.

The Ilyushin Il-20M (Russian: Ильюшин Ил-20М , NATO code name : "Coot-A" ) is a COMINT / ELINT variant of the Ilyushin Il-18. It was first observed by NATO in 1978.'
