Floyd Westerman, also known as Kanghi Duta i.e. “Red Crow” in Dakota (August 17, 1936 – December 13, 2007), was a Sioux musician, political activist, and actor. After establishing a career as a country music singer, later in his life, he became a leading actor depicting Native Americans in American films and television. He is sometimes credited simply as Floyd Westerman. He worked as a political activist for Native American causes.

He was born Floyd Westerman on the Lake Traverse Indian Reservation, home of the Sisseton Wahpeton Oyate, a federally recognized tribe. It is one of the tribes of the Eastern Dakota subgroup of the Great Sioux Nation, living within the U.S. state of South Dakota. His indigenous name Kanghi Duta means “Red Crow” in Dakota (one of the three Sioux related languages).

At the age of 10, Westerman was sent to the Wahpeton Boarding School, where he first met Dennis Banks (who as an adult became a leader of the American Indian Movement). There Westerman and other boys were forced to cut their traditionally long hair and forbidden to speak their native languages. This experience would profoundly impact Westerman’s later life. As an adult, he championed his own heritage.

He graduated from Northern State University with a B.A. degree in secondary education. He served two years in the US Marines, before beginning his career as a singer.
