Dulduityn Danzanravjaa (1803–1856, Mongolian: Дулдуйтын Данзанравжаа) was a prominent Mongolian writer, composer, painter, Buddhist scholar, physician and the fifth Noyon Khutagt, the Lama of the Gobi. His name is a Mongolian adaptation of the last part of the Tibetan name Lobsang Tenzin Rabgye given to Danzanravjaa by the fourth Bogd Gegeen on his visit to the Mongolian capital, Urga (present-day Ulaanbaatar), in 1812 – where Danzanravjaa was also recognized as an Incarnate Lama (Tib: Tulku). There are several versions concerning the origins and use of "Dulduityn". He was the fifth incarnation of the Gobi Noyon Khutagt, which is the title of a prominent line of tulkus of the Nyingmapa lineage of Tibetan Buddhism in Mongolia and was found by the personal attendant of the fourth Noyon Khuta
