Elsa the lioness (c. 28 January 1956 – 24 January 1961) 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.
Her story is told in several books by the Adamsons, as well as the 1966 motion picture Born Free.
