Elsa the lioness was a female lion raised along with her sisters "Big One" and "Lustica" by game warden George Adamson and his wife Joy Adamson after they were orphaned at only a few days old. Though her two sisters eventually went to the Netherlands' Rotterdam Zoo, Elsa was trained by the Adamsons to survive on her own, and was eventually released into the wild.

George Alexander Graham Adamson MBE, also known as the Baba ya Simba, was a British wildlife conservationist and author based in Kenya. His wife Joy Adamson related in her best-selling book Born Free (1960) the couple's life with Elsa the Lioness, an orphaned lioness cub they raised and later released into the wild.
