Orda Ichen (Lord Orda, Орд эзэн ("Ord ezen")) was a Mongol Khan and military strategist who ruled eastern part of the Ulus of Jochi during the 13th century.

Orda Ichen ( c. 1204-1251 CE) is credited for founding the Blue Horde; he was the eldest son of Jochi and the first grandson of Genghis Khan. At the death of his father and grandfather, Orda Khan inherited the Eastern portions of his father’s lands; while he was the elder, he nevertheless agreed that his younger brother Batu Khan ruled the whole Jochid Ulus (also known as the Golden Horde). This mainly consisted of the territories between Lake Balkhash and the Volga river; it was in these lands that Orda eventually founded the Blue Horde (also known as the Koke Orda). West of the Volga river were the lands of his younger brother Batu, who became the first ruler of the White Horde and the supreme Khan of the Golden Horde. The Great Khan Guyuk ordered Temuge Otchigin, who tried to illegally usurp the throne for himself, to be investigated by Orda and Mongke in c.1246.
