O-Six (2006–2012), also known as 832F or "The 06 Female", was a female gray wolf, whose death by hunting just outside the protected area of Yellowstone National Park stirred debate about the hunting and protection of wolves in Wyoming, Montana and Idaho. The bestselling book American Wolf focused on O-Six's life and on conservation policies in the Yellowstone region.
