General Batista Tagme Na Waie, also transliterated as Batista Tagme Na Wai (born 1949, Catió, Portuguese Guinea – died 1 March 2009), was chief of staff of the army of Guinea-Bissau until his assassination in 2009.

A participant in the junta that overthrew João Bernardo Vieira in the 1990s and a veteran of the Guinea-Bissau War of Independence,[1] Na Waie was a member of the Balanta ethnic group.

He had been appointed chief of staff as a result of the October 2004 murder of his predecessor, Verissimo Correia Seabra; IRIN has described him as a "consensus figure put forward by the military establishment which the government felt forced to accept".

After Tagme Na Wai became Chief of Staff of the Armed Forces, he announced the reintegration of 65 senior officers into the military, including Sanha, on 1 December 2004; Na Wai appointed Sanha as his naval advisor.

[2] Army spokesman Zamora Induta did, however, say that Vieira had been involved in Na Waie's assassination.
