A protest held by 50,000 people in Conakry, Guinea, was forcefully disrupted by the military junta, resulting in at least 157 deaths and over 1,200 injuries.

The 2009 Guinean protests were an opposition rally in Conakry, Guinea on 28 September 2009, with about 50,000 participants protesting against the junta government that came to power after the 2008 Guinean coup d'état in December. The protest march was fueled by the indication of junta leader Captain Moussa Dadis Camara breaking his pledge to not run in the next presidential vote due in January 2010. The government had already banned any form of protests until 2 October. When the demonstrators gathered in a large stadium, the security forces opened fire at them. At least 157 demonstrators were killed, 1,253 injured and 30, including Cellou Dalein Diallo, the leader of the opposition Union of Democratic Forces of Guinea (UDFG), were arrested and taken away in lorries.

Conakry is the capital and largest city of Guinea. A port city, it serves as the economic, financial and cultural centre of Guinea. Its population as of the 2014 Guinea census was 1,660,973.
