Yerutömör (Chinese: 月魯帖木兒, Mongolian: Ерүтөмөр) was a prince of the Yuan dynasty of China.
Yerutömör participated in the assassination of the Yuan emperor Gegeen Khan along with the main plotter Tegshi (step-son of Temuder).
After Yesün Temür took power, Yerutömör was officially announced the king of Anxi.
Jayaatu Khan, upon his accession to the throne, eliminated people who participated in the assassination of Gegeen.
Since Yerutömör was one of the key figure during the Nanpo Incident, he was deprived of his title and exiled to the province of Yunnan under the charge of treason.
