Jadonang Malangmei (1905-1931), popularly known as Haipou Jadonang, was a Naga spiritual leader and political activist from Manipur, British India. He established the Heraka religious movement, which was based on the ancestral Naga religion, and declared himself to be the "messiah king" of the Nagas. His movement was widespread in the Zeliangrong territory before the conversion to Christianity. He also espoused the cause of an independent Naga kingdom, which brought him in conflict with the colonial British rulers of India. He was hanged by the British in 1931, and succeeded by his cousin Rani Gaidinliu.

Nagas are various ethnic groups native to northeastern India and northwestern Myanmar. The groups have similar cultures and traditions, and form the majority of population in the Indian state of Nagaland and Naga Self-Administered Zone of Myanmar (Burma); with significant populations in Manipur, Arunachal Pradesh and Assam in India; Sagaing Region and Kachin State in Myanmar.
