Bordjigin or Borjigin (Mongolian: Боржигин; Chinese: 博爾濟吉特; pinyin : Bó' ěrjìjítè) was the clan of the family of Gengis Khan and thus of its successors.

This family reigned on the Mongolian Empire plain at the 13th century and, in 1271, Kubilai Khan which, as a direct descendant of Gengis, also established the Dynastie Yuan in China. The clan continued to reign on the empire for most of the next century.

In 1368, under Togoontomor, the clan lost China but the family members continued to reign on the Mongolia at the 17th century and was strongest of the 49 Mongolian banners under the Qing.

“Bordjigin” is from now on a common family name in Mongolia.
