Ernie LaPointe (born 1948) is an Indigenous American Sun Dancer, author, and orator,[4] known for being the great-grandson of Sitting Bull (Tȟatȟáŋka Íyotake), chief of the Hunkpapa Lakota.

Before his mother's death Lapointe was told that a day might come when it will be important for him to set the record straight about his great-grandfather, Sitting Bull.

[12] LaPointe then began writing a book Sitting Bull: His Life and Legacy and speaking to audiences throughout the country and abroad about his great-grandfather.

[13] LaPointe and his wife spend much of their time traveling throughout the United States and abroad speaking at universities, museums, and film festivals about the history of Sitting Bull as well as the cultural heritage of the Lakota people.

A lock of hair and leggings attributed to Sitting Bull were in the collection of the National Museum of Natural History, Smithsonian Institution.
