The Jalkhanz Khutagt Sodnomyn Damdinbazar (Mongolian: Жалханз Хутагт Содномын Дамдинбазар; 1874 – June 23, 1923) was a high Buddhist incarnation from northwestern Mongolia who played a prominent role in the country's independence movement in 1911–1912.

From the ages of 16 to 20 he was instructed in Tibetan and Mongolian script, mathematics, astrology, and religious matters as a śrāmaṇera in a monastery at Ikh Hüree (modern Ulan Bator).

He was appointed Minister for the Pacification of the Western Border Areas during the Bogd Khanate and together with Khatanbaatar Magsarjav, Manlaibaatar Damdinsüren, Togtokh Taij, and Ja Lama took part in the liberation of Khovd.

In 1922 Dogsomyn Bodoo resigned as prime minister in the face of accusations that he conspired with reactionary enemies (including Ja Lama and the U.S. Consul in Kalgan) to overthrow the government.

Looking to quell resulting religious anger (Bodoo was a lama) party leaders including Sükhbaatar invited Damdinbazar to become the next prime minister.
