{{#invoke:Infobox|infobox}} {{#invoke:Side box|main}} 18 (eighteen) is the natural number following 17 and preceding 19.

In speech, the numbers 18 and 80 are sometimes confused. When carefully enunciated, they differ in which syllable is stressed: 18 {{#invoke:IPAc-en|main}} vs 80 {{#invoke:IPAc-en|main}}. However, in dates such as 1864, or when contrasting numbers in the teens, such as 17, 18, 19, the stress shifts to the first syllable: 18 {{#invoke:IPAc-en|main}}. In some dialects, such as General American, there is little confusion because the single t sound in 80 becomes a d-like flap [ɾ], whereas the double t sound in 18 does not.
