The Dupleix class consisted of three armored cruisers built for the French Navy at the beginning of the 20th century. Designed for overseas service and armed with eight 164.7-millimeter (6.5 in) guns, the three ships of the class were smaller and less powerfully armed than their predecessors.

The French cruiser Dupleix was the lead ship of her class of three 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 1903, Dupleix was initially assigned to the Atlantic Division as its flagship. The ship spent 1906 to 1909 in reserve before she was sent to the Far East in 1910, again serving as a flagship.
