Dundgovi or Dundgobi (Mongolian: Дундговь, Middle Gobi) is one of the 21 aimags (provinces) of Mongolia. It is located in the south of the country, approximately 245 kilometers (152 mi) south of Ulaanbaatar. Its capital is Mandalgovi. Dundgovi is the second least populated Province.

Dundgovi province is situated in the south of the country about 240 kilometres or 150 miles from capital city Ulaanbaatar. It consists largely of semi-arid steppe and low hills. Temperatures in the summer may top 32 °C or 90 °F, while winter temperatures may dip below −30 °C or −22 °F. Precipitation is scarce, and air humidity is low.

Seasonal climatic problems include spring sandstorms and winter zud.

There is no commercial air transport to the Dundgobi province. Public transportation includes bus but many of the more rural sums are not on the mass transport lines. Much travel is done via mikrs (micro-bus or Russian furgon) or by private jeeps. The capital, Mandalgovi, is connected to Ulaanbaatar by a 300 km (190 mi) paved road completed in 2013.

Many locals own 250 cc motorcycles, which they use as their main mode of transportation.

The province's main industry is animal husbandry and livestock products (such as wool, cashmere). The Dundgobi province is also noted among Mongolian locals for its airag (fermented horse milk), a traditional Mongolian alcoholic drink.
