Ibrahim Abatcha (1938 – February 11, 1968) was a Muslim Chadian politician reputed of Marxist leanings and associations. His political activity started during the decolonization process of Chad from France, but after the country's independence he was forced to go in exile due to the increasing authoritarism of the country's first President François Tombalbaye. To overthrow Tombalbaye he founded in Sudan in 1966 the FROLINAT, of which he was the first leader and field commander. Two years later he was killed in a clash with the Chadian Army.
