The Stele of Genghis Khan (Mongolian: Чингисийн чулууны бичиг, Russian: Чингисов камень), also known as the Stele of Yisüngge, is a granite stele inscribed with a dedication to Yisüngge, nephew of Genghis Khan, for performing a feat of archery during a gathering of noyans after the Mongol conquest of the Khwarazmian Empire, dated to c. 1224–1225.^[2] It was discovered in 1802, close to the remains of Khirkhira,^[3] a 13th-century settlement in Transbaikal that served as the center of the territories of Qasar and his descendants. Since 1936 it has kept at the Hermitage Museum in Saint Petersburg, Russia.

It is important for containing the first known inscription in Mongolian Script.^[4]

According to the inscription, the stele commemorates an event that occurred in the settlement of Buqa Sočiγai, whose location is unknown. It was found, however, near Khirkhira in the Transbaikal region, which according to the Jami' al-tawarikh, was part of the Ulus of Qasar.^[5]

Copies of the stele exist in various museums, including the National Museum of Mongolia in Mongolia and the Inner Mongolia Museum in Inner Mongolia.

A volumetric model of the stele was created in 2017 by the Hermitage's Laboratory for Science Restoration of Precious Metals, so that an exact polymer replica could be grown layer-by-layer. The replica was presented to Mongolia in 2019 to be placed in the under-construction Genghis Khan Museum in Ulaanbaatar.^[3]

The text of the stele consists of 5 lines - the first line, containing the name Genghis Khan is elevated as a sign of respect, as is the fourth line that contains the name of his nephew Yisüngge (but lower than the first).^[7] The scribe's writing style is also uncommon, as they write a few distinct letters with the same forms, such as ᠭ(γ) and ᠬ(q), making the stele somewhat difficult to read.

According to Igor de Rachewiltz (2010), the inscription reads (with letters in parentheses being unclear):

As the ald is a unit of measure equal to the length between someone's outstretched arms, approximating 160 cm = one ald results in 335 ald being equal to ~536 m.^[8]
