Jancita Eagle Deer was a Brulé Lakota who lived on the Rosebud Indian Reservation in South Dakota. She was notable for accusing William Janklow of having raped her in January 1967 when he was a poverty lawyer and Director of the Rosebud Sioux Legal Services program on the reservation. She had worked as his babysitter. At the time the Bureau of Indian Affairs (BIA) and the Federal Bureau of Investigation (FBI) did not prosecute the case.

William John Janklow was an American lawyer and politician and member of the Republican Party who holds the record for the longest tenure as Governor of South Dakota: sixteen years in office. Janklow had the third-longest gubernatorial tenure in post-Constitutional U.S. history at 5,851 days.
