Ali Badjo Gamatié (born 1957)[1] is a Nigerien politician and civil servant who served as Prime Minister of Niger from October 2009 to February 2010.

[3] As Finance Minister, Gamatié was an international advocate for the total cancellation of foreign debts[4] of Niger and other Heavily Indebted Poor Countries (HIPC).

[5][6] As Finance Minister, he also raised questions about the accountability and representativeness of non-governmental organizations and civil society groups operating in Niger and elsewhere.

[8] In July 2003, journalist Mamane Abou of Le Républicain newspaper in Niamey was arrested for defamation after he wrote an article accusing Gamatié and Hama Amadou of using unauthorized Treasury funds to pay for government contracts.

[21] According to one of the junta leaders, Colonel Djibrilla Hamidou Hima, the ministers "still under surveillance" had held "very sensitive portfolios" and therefore it was necessary "to ensure their security".
