The Yankton Indian Reservation is the homeland of the Yankton Sioux Tribe of the Dakota tribe.

Zitkala-Ša, also Zitkála-Šá, was a Yankton Dakota writer, editor, translator, musician, educator, and political activist. She was also known by her Anglicized and married name, Gertrude Simmons Bonnin. She wrote several works chronicling her struggles with cultural identity, and the pull between the majority culture in which she was educated, and the Dakota culture into which she was born and raised. Her later books were among the first works to bring traditional Native American stories to a widespread white English-speaking readership.
