Arjun Munda (born 5 January 1968 in Khrangajhar Jamshedpur) is an Indian politician, former Member of Parliament to the 15th Lok Sabha. He resigned the 15th Lok Sabha membership on 26 February 2011, and is currently Chief Minister of Jharkhand.

He is married to Meera Munda. On May 9th, 2012 a helicopter carrying Munda and his wife to Chaibasa crash landed at the Birsa Munda Airport in Ranchi. Although the minister was reported to have been injured, both of them survived the accident.

His political career began in the 1980s as part of the Jharkhand movement, spearheaded by the Jharkhand Mukti Morcha. This movement sought to create a tribally-dominated state from the southern area of India's northern Bihar state. Munda's political clout grew due to his focus on helping tribals and other backwards. In 1995, he was elected to the Bihar state assembly, representing Kharswan. He retained that seat in 2000 and 2005 elections, but as of 2000, he was a member of the Bharatiya Janata Party (BJP)

Jharkhand was formed in 2000, with the BJP forming the first government under Babulal Marandi. Arjun Munda served as the Social Welfare Minister in his cabinet. In 2003, as the non-BJP Legislators supporting the government called for Marandi's replacement, it was Munda, viewed as a strong tribal leader, who was considered the best alternative. Munda took the position of Chief Minister on 18 March 2003 and held it until his resignation on 2 March 2005, which occurred after inconclusive state elections and the intervention of the state's governor, Syed Sibtey Razi.
