Bavet (Khmer: បាវិត, Bavĭt [ɓaːʋət]) is the largest city in Svay Rieng Province, Cambodia. An international border crossing between Cambodia and Vietnam, its counterpart across the border is Mộc Bài of Tây Ninh Province, Vietnam.

Bavet is one of the "special economic zones" (SEZ) of Cambodia and there were established textile industries and bicycles factories. However, the most evident economic activity of Bavet are the casinos, fraud factories and cockfighting rings, attended by Vietnamese.

In accordance with decentralization politics experienced by Cambodian government, Bavet commune has become a municipality by sub-decree in December 2008. There are about 10–12 (from small to large) casinos and 6 to 7 developing areas set up by foreign investors. The city is in a growing state. The 2 km-long Neak Loeang bridge funded by Japan has been finished in April 2015. It is the longest bridge in Cambodia.

The proposed Ho Chi Minh City–Phnom Penh railway is planned to pass through Bavet.
