The Codex Cairensis (also: Codex Prophetarum Cairensis, Cairo Codex of the Prophets) is a Hebrew manuscript containing the complete text of the Hebrew Bible Nevi'im (prophets). It has been described as "the oldest dated Hebrew Codex of the Bible which has come down to us". It contains the books of the Former Prophets (Joshua, Judges, Samuel, and Kings) and Latter Prophets (Isaiah, Jeremiah, Ezekiel and the book of the twelve Minor Prophets). It comprises 575 pages including 13 carpet pages.
According to its colophon, it was written complete with punctuation by Moses ben Asher in Tiberias "at the end of the year 827 after the destruction of the second temple" (this corresponds to the year 895 CE). It was given as a present to the Karaite community in Jerusalem, and taken as booty by the Crusaders in 1099. Later it was redeemed and came into the possession of the Karaite community in Cairo. When the Karaite Jews left Egypt they deposited the codex in 1983, in the Hebrew University in Jerusalem, with document to prove it, where it is kept in a secure room on the floor below the Hebrew Manuscript collection. The Codex was brought back to Jerusalem by a comity of six persons.
Although according to its colophon the codex was written by a member of the Ben Asher family, Lazar Lipschütz and others observed that, within the masoretic tradition, Codex Cairensis seems to be closer to Ben Naphtali than to Ben Asher.
