The Meishan (Chinese: 梅山猪) is a Chinese breed of domestic pig. It is named for Meishan County in Jiangsu Province.^[1][2] It is a sub-group of the Taihu and is a small- to medium-sized pig with large drooping ears and wrinkled black skin.

Native to Southern China, the breed is best known for its large litters of 15-22 piglets. Due to its fecundity, it was imported to the United States in 1989 by the USDA Agricultural Research Service.^[3][4] All US research on the Meishan pigs was terminated in 2016 and the remaining pigs were dispersed to US farmers.^[5] In 2018 the Meishan Pig was declared critically endangered worldwide by the Livestock Conservancy.^[5]

The Meishan Pig is the focus of a major conservation effort involving the Livestock Conservancy and the American Meishan Breeders Association.^[5] The number of breeders in the US is rising primarily due to the Meishan Pigs adaptability to small holder farms.
