Eljigidei Noyan (Mongolian: ᠡᠯᠵᠢᠭᠲᠡᠢ ᠨᠣᠶᠠᠨ, d. 1251) was a Mongol commander in Persia.
He was a commander of the Kheshig during reign of Ögedei, the second ruler of the Mongol Empire and the third son of Genghis Khan.
He departed from Mongolia in September 1247 and arrived in Talas in April 1248, which coincided with Güyük's death.
This advance was, ideally, to be conducted in alliance with Louis IX of France, in concert with the Seventh Crusade.
However, Güyük's sudden death made Eljigidei postpone operations until after the interregnum.
