Suleiman II, also known as Rukn ad-Din Suleiman Shah (Persian: رکن الدین سلیمان شاه), was the Seljuk Sultan of Rûm between 1196 and 1204.
He fought neighbouring rulers and expanded the territories of the Sultanate. In 1201 he conquered Erzurum, giving it as a fief to Mughith al-Din Tugrulshah in 1202. Successful in the wars with the Byzantines, he was routed by the Georgians in the Battle of Basian of 1203.
