Chandmani-Ondor (Mongolian: Чандмань-Өндөр) is a sum of Khövsgöl aimag.

The center, officially named Khukhuu (Mongolian: Хөхөө) is located 190 km north-northeast of Mörön and 758 kilometers from Ulaanbaatar.

In 2004, there were roughly 41,000 heads of livestock, among them 10,000 sheep, 13,000 goats, 14,000 cattle and yaks, and 4,100 horses, but no camels.

[1] Some locals believe that Alan Goa, one of the more prominent ancestors of Genghis Khan mentioned in the Secret History of the Mongols, hails from the Arig gol river that runs through Chandmani-Öndör.
