Frank Bennett Fiske (June 11, 1883 – July 18, 1952) was an early-20th-century photographer primarily active among the Lakota (Sioux) on Standing Rock Indian Reservation in North and South Dakota.

Frank Fiske, born in 1883 at Fort Bennett in Dakota Territory, grew up on the Standing Rock Indian Reservation, where he developed a deep admiration for the Sioux nation. At 17, he took over a photography studio in Fort Yates, continuing the legacy of renowned photographers like Orlando Scott Goff. Fiske captured the history and culture of the Lakota people, publishing books such as The Taming of the Sioux (1917) and Life and Death of Sitting Bull (1933). He served briefly in World War I, married Angela Cournoyer, and had a daughter, Francine. In 1950, Fiske received the North Dakota Art Award for his contributions to photography. He passed away in 1952, and his extensive collection of Indian photographs was later housed at the State Historical Society of North Dakota.
