Altanochir (1887 – ?), also known under the Chinese name of Jin Yongchang, was an Inner Mongolian politician under the Republic of China and the Mengjiang government.
When Altanochir was in his youth, he was one of a small number of Mongolian students sent to Japan under the sponsorship of Prince Gungsangnorbu of Right Harqin Banner. He would go on to become a member of the Inner Mongolian People's Revolutionary Party. He would go on to join the Mengjiang government in 1937, and rose to the position of Minister of Communications in 1939. He also served as first head of the Mongolian Cultural Centre (蒙古文化館) in Hohhot. In September 1939, he was succeeded by Idchin (伊德欽) in that position, and became rector of the Mongolian Academy (蒙古學院).
Altanochir was known to have remained in mainland China following the establishment of the People's Republic of China in 1949, but his fate after that point is unknown. His son Togtakhu (托克托琥) was active in the Kuomintang, and went on to teach at the Mongolian and Tibetan School in Beijing.
