The South Dakota State Penitentiary is a state prison located in South Dakota's largest city, Sioux Falls. The building's industry shop makes several things for the state, including woodwork and license plates. The State Penitentiary also houses South Dakota's death row for men and the state's execution chamber.

Death row, also known as condemned row, is a place in a prison that houses inmates awaiting execution after being convicted of a capital crime and sentenced to death. The term is also used figuratively to describe the state of awaiting execution, even in places where no special facility or separate unit for condemned inmates exists. In the United States, after an individual is found guilty of a capital offense in states where execution is a legal penalty, the judge will give the jury the option of imposing a death sentence or life imprisonment without the possibility of parole. It is then up to the jury to decide whether to give the death sentence; this usually has to be a unanimous decision. If the jury agrees on death, the defendant will remain on death row during appeal and habeas corpus procedures, which may continue for several decades.
