Southern Lakes is an electoral district in rural Yukon which returns a member (known as an MLA) to the Legislative Assembly of the Yukon in Canada. In accordance with the Yukon Electoral District Boundaries Act (2024), it was first contested at the 2025 Yukon general election.
The riding is part of the traditional territory of the Carcross/Tagish First Nation, the Teslin Tlingit Council, the Kwanlin Dün First Nation, and the Ta'an Kwach'an Council. It was bordered by the rural ridings of Pelly-Nisutlin, Kluane, and Lake Laberge, as well as the rural-residential riding of Mount Lorne south of Whitehorse.
Southern Lakes was originally created as part of the 2002 Electoral Boundaries Commission when the riding of Ross River-Southern Lakes was divided into the ridings of Southern Lakes and Pelly-Nisutlin. Southern Lakes retained the communities of Carcross and Tagish and merged with the bedroom community of Marsh Lake.
In the 2009 electoral redistribution, the riding was dissolved, combining with the Hamlet of Mount Lorne to form the new riding of Mount Lorne-Southern Lakes.
In accordance with the Yukon Electoral District Boundaries Act (2024), Mount Lorne-Southern Lakes was split into Marsh Lake-Mount Lorne-Golden Horn and Southern Lakes at the 2025 Yukon general election.
