"Annie Get Your Gun" is a musical with lyrics and music by Irving Berlin and a book by Dorothy Fields and her brother Herbert Fields. The story is a fictionalized version of the life of Annie Oakley (1860–1926), a sharpshooter who starred in Buffalo Bill's Wild West, and her romance with sharpshooter Frank E. Butler (1847–1926).

William Frederick "Buffalo Bill" Cody (February 26, 1846 – January 10, 1917) was an American soldier, bison hunter, and showman. He was born in Le Claire, Iowa Territory (now the U.S. state of Iowa), but he lived for several years in his father's hometown in modern-day Mississauga, Ontario, Canada, before the family returned to the Midwest and settled in the Kansas Territory.

One of the most famous and well-known figures of the American Old West, Buffalo Bill's legend began to spread when he was only 23. Shortly thereafter he started performing in shows that displayed cowboy themes and episodes from the frontier and Indian Wars. He founded "Buffalo Bill's Wild West" in 1883, taking his large company on tours in the United States and, beginning in 1887, in Great Britain and continental Europe.
