Sher Mohammad Marri (Balochi: میر شير محمد مری) was the chief of the Marri Baloch tribe in Pakistan, and an early leader in the Parrari movement which would lead to the formation of the Baloch Liberation Army, a militant nationalist group.

Sher Mohammad was the first Baloch to use the tactics of modern guerrilla warfare against the government.

In the early 1960s, his Parari fighters attacked the Pakistani Armed Forces in the Marri area and in Jahlawan under Mir Ali Muhammad Mengal.

[4] Upon his release in the late 1970s, Marri went into exile in Pakistan's Marxist neighbour, the Democratic Republic of Afghanistan.

[citation needed] Following the fall of the Communist Afghan government in April 1992, Marri briefly returned to Pakistan but then he went to India.
