Habibullah Kalakani (; 19 January 1891 – 1 November 1929, "The Bandit King") was King of Afghanistan from January to October 1929 after deposing Amanullah Khan with the help of various Afghan tribes who opposed the modernization of Afghanistan. After gaining power in Kabul, he named himself Habibullah Khadem-e Din-e Rasulallah ("The servant of the religion of the messenger of God"). He was defeated and overthrown nine months later by Mohammed Nadir Khan. Khalilullah Khalili, a Kohistani poet laureate, depicts Kalakani as a mujahid "against an infidel king."
