Huron South was a federal electoral district in Ontario, Canada, that was represented in the Canadian House of Commons from 1867 to 1935. It was created by the British North America Act of 1867 which divided the County of Huron into two ridings: Huron North and Huron South.
In 1872, the County of Huron was divided into three ridings, and Huron Centre was created. The South Riding was defined to consist of the Townships of Goderich, Stanley, Hay, Stephen, Usborne and the Village of Clinton.
In 1882, the South Riding was redefined to consist of the townships of McKillop, Hullett, Tuckersmith, Stanley and Hay, the town of Seaforth and the village of Bayfield.
In 1903, the county of Huron was divided into three ridings: Huron East, Huron West and Huron South. Huron South was redefined to exclude the township of Hullett, and include the townships of Stephen and Usborne, and the villages of Exeter and Hensall.
In 1914, the county of Huron was divided into two ridings: Huron North and Huron South. Huron South was expanded to include the townships of Hullet and Goderich, and the town of Clinton.
In 1924, Huron South was redefined to consist of the part of the county of Huron lying south of and excluding the town of Goderich, and north of and including townships of Goderich, Hullett, and McKillop.
