Abū Saʿīd Janibek Bahadur Khan bin Barak Sultan (Kazakh: ابو سعید جانی بیک خان بن براق سلطان, Әбу Саид Жәнібек Баһадүр хан бин Барақ сұлтан, Äbu Saïd Jänıbek Bahadür Han bïn Baraq Sultan), otherwise known by his shortened regal name Janibek Khan, was a co-founder and second Khan of the Kazakh Khanate from 1473 to 1480.

From his wife Jahan Begum Khanum, Janibek had nine sons: Qasim (who became his successor), Mahmud, Iranji, Ithik, Janysh, Qanabar, Tenish, Usuk, and Juak.

Janibek's father was Barak Khan, who was poisoned by the emirs of the former White Horde.

For his wisdom, he was given the title "Az", meaning "the wise" in the Kazakh language, and so was called Az-Janibek.
