Ansumane Mané (c. 1940 – 30 November 2000) was a Bissau-Guinean soldier who led a 1998 uprising against the government of President João Bernardo Vieira, which caused a brief but bloody civil war.

[2][3][1] In a letter published in early April 1998, he in turn made the same accusation against the Minister of Defense, Samba Lamine Mané, and other officers; he also alleged that Vieira had permitted the arms smuggling and claimed that he was suspended as Chief of Staff in connection with "shady plan to mount a coup d'état".

[4] According to Birgit Embaló, soldiers and war veterans in Guinea Bissau were upset at their pay, leading the military to self-finance itself through smuggling.

After Vieira was deposed on 7 May 1999 in a renewed outbreak of fighting,[2][6][7] Mané became temporary head of state (official title: Chairman of the Supreme Command of the Military Junta) until 14 May when Malam Bacai Sanhá, the president of the National People's Assembly, was installed as acting president.

When issuing a communique claiming that the situation was calm, he signed it as the head of the junta, which had previously been dissolved when Ialá was elected president.

[10] Among Mané's most prominent allies was Naval Chief of Staff Mohamed Lamine Sanha who was also assassinated a few years later.
