The Second Battle of Garua took place from 31 May to 10 June 1915 during the Kamerun campaign of the First World War in Garua, German Kamerun. The battle was between a combined French and British force and defending German garrison and resulted in an Allied victory.

The Kamerun campaign took place in the German colony of Kamerun in the African theatre of the First World War when the British, French and Belgians invaded the German colony from August 1914 to March 1916. Most of the campaign took place in Kamerun but skirmishes also broke out in British Nigeria. By the Spring of 1916, following Allied victories, the majority of German troops and the civil administration fled to the neighbouring neutral colony of Spanish Guinea. The campaign ended in a defeat for Germany and the partition of its former colony between France and Britain.
