Kenan (also spelled Qenan, Kaynan, Caynam or Cainan) (Hebrew: קֵינָן‎, Modern: Qēnan, Tiberian: Qēnān; Arabic: كِنَاْنْ, romanized: Kinān; Biblical Greek: Καϊνάμ, romanized: Kaïnám) is an Antediluvian patriarch first mentioned in the Book of Genesis in the Hebrew Bible.

The Sefer ha-Yashar describes Cainan, the possessor of great astrological wisdom, which had been inscribed on tables of stone, as the son of Seth; i.e., the antediluvian Kenan grandson of Seth according to the Bible.

According to Genesis 5:9–14, Kenan was a son of Enosh and a grandson of Seth.

According to the Book of Jubilees, Kenan's mother was Noam, wife and sister of Enosh; and Kenan's wife, Mualeleth, was his sister.

The following family tree has been constructed from a variety of biblical and extra-biblical sources: Kenan is mentioned in Islam in the various collections of tales of the Islamic prophets, which honor him in an identical manner.
