This is a timeline of women's suffrage in South Dakota. The early history of women's suffrage in the state is shared with North Dakota. When South Dakota became a state, it held a voter referendum in 1890 on an equal suffrage amendment. This effort failed, but suffragists continued to organize and lobby the legislature to pass voter referendums. None passed until 1918. South Dakota ratified the Nineteenth Amendment on December 4, 1919.
