Nniiden Iljušin Il-18 on suuri potkuriturbiinikone, joka lensi ensimmäisen kerran vuonna 1957 ja josta tuli yksi aikansa tunnetuimmista Neuvostoliiton lentokoneista. Il-18 oli yksi maailman tärkeimmistä matkustajakoneista useiden vuosikymmenien ajan, ja sitä vietiin laajalti. Lentokoneen kestävyyden ansiosta monet esimerkit saavuttivat yli 45 000 lentotuntia, ja tyyppi on edelleen toiminnassa sekä sotilaallisissa että (vähemmässä määrin) siviilivalmiuksissa. Il-18: n seuraaja oli pidemmän kantaman Iljušin Il-62.
