'''Dua Kumayl''' ({{lang-ar|دعاء كميل}}, {{Literal translation|supplication of Kumayl}}) is a ''[[dua|]]''dua'']] or supplication attributed to [[Ali]], the cousin and son-in-law of the [[Islam|Islamic]] [[Prophets and messengers in Islam|prophet]] [[Muhammad]], who taught it to his companion, [[Kumayl ibn Ziyad]]. This supplication is used by Muslims to ward off evil and is particularly well-known among [[Shia Islam|Shia]] Muslims.
