Zengpiyan (Chinese: 甑皮岩; pinyin: Zèngpíyán) is a Neolithic cave site in southern China. It is located in the Guilin region on the south-western fringes of the Dushan Mountain (Dú Shān 独山) in the autonomous region Guangxi and is considered to be one of the most important cave sites of the Neolithic in China as it is one of the many independent centers for the introduction of animal domestication and pottery. The assertion that the pig was domesticated at this site remains controversial and has not yet been answered conclusively.
