The Gueydon-class cruiser was a three-ship class of armored cruisers built in the first decade of the twentieth century for the French Navy.

Designed by the naval architect Emile Bertin, the Gueydon-class ships were intended to be smaller and cheaper than the preceding armored cruiser design, the Jeanne d'Arc. Like the older ship, they were intended to fill the commerce-raiding strategy of the Jeune École. The ships measured 137.97 meters (452 ft 8 in) long overall with a beam of 19.38 meters (63 ft 7 in) and had a maximum draft of 7.67 meters (25 ft 2 in). They displaced 9,367 metric tons (9,219 long tons). They had a crew of 566 officers and enlisted men.

The Gueydon class had three vertical triple-expansion steam engines, each driving a single propeller shaft. Steam for the engines was provided by 20 or 28 boilers and they were rated at a total of 19,600–22,000 indicated horsepower (14,600–16,400 kW) that gave them a speed of 21–22 knots (39–41 km/h; 24–25 mph). The ships carried up to 1,575 metric tons (1,550 long tons; 1,736 short tons) of coal and could steam for 8,500 nautical miles (15,700 km; 9,800 mi) at a speed of 10 knots (19 km/h; 12 mph).

The ships of the Gueydon class had a main armament that consisted of two 40-caliber 194 mm (7.6 in) guns that were mounted in single gun turrets, one each fore and aft of the superstructure. Their secondary armament comprised eight 45-caliber quick-firing (QF) 164 mm (6.5 in) guns in casemates. For anti-torpedo boat defense, they carried four 45-caliber QF 100 mm (3.9 in) guns on the forecastle deck, ten QF 47 mm (1.9 in) and four QF 37 mm (1.5 in) Hotchkiss guns. They were also armed with two submerged 450-millimeter (17.7 in) torpedo tubes.
