The French cruiser Desaix was one of three Dupleix-class armored cruisers built for the French Navy in the first decade of the 20th century. Designed for overseas service and armed with eight 164.7-millimeter (6.5 in) guns, the ships were smaller and less powerfully armed than their predecessors. Completed in 1904, Desaix was initially assigned to the Mediterranean Squadron before she was transferred to the Atlantic Division the following year, where she served as a flagship. The cruiser returned to the Mediterranean in 1906, but only remained there for a year before rejoining the Atlantic Division. Desaix was in reserve from 1909 to 1914.
