Mangal Bagh (born 1973),  also known as Mangal Bagh Afridi, is the leader (and according to some reports, founder) of Lashkar-e-Islam, a militant organization operating in Khyber Agency, Pakistan. Several Pakistani newspapers have referred to him by title as Haji Amir Mangal Bagh. He is from the Bara tehsil, and belongs to the Sepah Afridi tribe.
Bagh is said to be a successor of Mufti Munir Shakir, a Deobandi cleric who established a pirate radio ministry in Khyber Agency in 2004 after being ejected from Kurram Agency by tribal elders for inciting sectarian hostility. When Shakir was ejected from Khyber Agency, he turned over his radio station to Bagh, a local driver, and Bagh then formed the militant group Lashkar-e-Islam. Nowadays he is somewhere in the Tirah Valley. But members of LeI are still in Bara and areas of Khyber Agency.
