Bai Yun (simplified Chinese: 白云; traditional Chinese: 白雲; lit. 'White Cloud'; born September 7, 1991) was the first female giant panda who was born at the Wolong Giant Panda Research Center in China. From September 1996 she lived at the San Diego Zoo for more than 20 years, until being returned to China in May 2019. Bai Yun gave birth to her sixth cub in 2012 since arriving at the San Diego Zoo, considered the most surviving pandas born at a breeding facility outside of native China. Bai Yun returned to China with her last-born (Xiao Liwu) as the 23-year conservation loan of the pandas came to an end between China and San Diego Zoo Global.
