Papyrus 18 (in the Gregory–Aland numbering), designated by 𝔓18, is an early copy of the New Testament in Greek.

It is unclear whether the papyrus was a scroll of Exodus later reused for a copy of Revelation or a leaf from a codex with miscellaneous contents.

[2] The Greek text of this manuscript is a representative of the Alexandrian text-type.
