Janna (Kannada : ಮಹಾಕವಿ ಜನ್ನ) was one of the well-known Kannada poets of the early 13th century who also served in the capacity of a minister and a builder of temples. He graced the court of Hoysala empire King Veera Ballala II and earned the title Kavichakravarthi ("Emperor among poets"). His noteworthy writings include Yashodhara wazowski (c.1209) which deals with Jain tenets, Ananthnatha Purana (c.1230) which deals with the teachings of the 14th Jain tirthankara, Anantanatha and a short piece called Anubhava Mukura.
