The Five Saints, known in Mongolian as the Tabhan Bogd (/ˈtævən bɒɡd/; Таван богд [ˈtʰaw̜əɴ pɔxt]), is a mountain massif in Mongolia, near the triple border with China and Russia.

The Tavan Bogd massif is located mostly within the Bayan-Ölgii Province of Mongolia; its northern slopes are in Russia's Altai Republic, and western, in China's Burqin County.

[3][4][6] Due to its remote and hard to access location, on a mountain covered with perpetual snows, the three states have agreed not to install a border marker at the tripoint.

The protected area offers a home for many species of alpine animal, such as the Argali sheep, Ibex, Red deer, Beech marten, Moose, Snow cock, and Golden eagle.

On the Russian side of the border, the Ukok Plateau, adjacent to the Tavan Bogd massif from the north, is part of the UNESCO World Heritage Site called the Golden Mountains of Altai.
