Carloman II (c. 866 - 12 December 884), King of West Francia, was the youngest son of King Louis the Stammerer and Ansgarde of Burgundy, and became king jointly with his brother Louis III of France on his father's death in 879. Initially some Frankish nobles advocated electing Louis III as the sole king, but eventually both brothers were elected kings. Although some doubts were cast upon the legitimacy of their birth, the brothers obtained recognition and in March 880 divided their father's realm at Amiens, Carloman receiving southern Kingdom of Burgundy and Kingdom of Aquitaine.

Meanwhile, the powerful Duke Boso of Provence had renounced his allegiance to both brothers and had been elected King of Provence. In the summer of 880 Carloman and Louis III marched against Boso, took Mâcon and the northern parts of his realm. Despite receiving help from their cousin Charles the Fat, who ruled East Francia and Kingdom of Italy the siege of Vienne lasted from August to November without success. Only in the summer of 882 Vienne was taken after being besieged by Richard, Count of Autun.

After the accidental death of Louis III in August 882, Carloman II became the sole king of West Francia. The kingdom was in a deplorable condition partly owing to repeated incursions from the Viking raiders, and his power was very limited by rebellious nobles, especially in Burgundy.

Carloman II died while hunting on 12 December 884 and was succeeded in the throne by his cousin, the Emperor Charles the Fat.
