Zavkhan (/ˈzaʊxɑːn/; Mongolian: Завхан ᠵᠠᠪᠬᠠᠨ [ˈt͡saw̜χəɴ]), also spelt Zaukhan or Zabhkhan, is one of the 21 aimags (provinces) of Mongolia, located in the west of the country, 1,104 km from Ulaanbaatar.

Locally, Zavkhan's environment is considered "Gobi-Khangai" (Говь хангай), since it connects the Gobi Desert in the south with the western Khangai Mountain Range and the broad lake basin of Khovd aimag.

The mountain is located in the 95,510 hectare Otgon Tenger Strictly Protected Area, about 60 km east of Uliastai.

Many forest, mountain and migratory birds can be found in the aimag, including rare snowcocks and bobwhites, as well as swans, vultures, falcons and hawks.

While Zavkhan's mineral wealth remains largely been unexploited, in 2012 the Golden Hill Project mine was built by Bayan Airag Exploration LLC outside of Durvuljin soum.
