Mount Lorne-Southern Lakes is an electoral district which returns a member (known as an MLA) to the Legislative Assembly of Yukon in Canada. It is one of the Yukon's eight rural ridings.
The district was first contested in the 2011 election. It was created by merging most of the former districts of Mount Lorne and Southern Lakes. The riding includes the Yukon communities of Carcross, Tagish, Marsh Lake, and Mount Lorne as well part of the traditional territory of the Carcross/Tagish First Nation, the Teslin Tlingit Council, and the Kwanlin Dün First Nation.
In accordance with the Yukon Electoral District Boundaries Act (2024), this riding will split into Marsh Lake-Mount Lorne-Golden Horn and Southern Lakes at the 2025 Yukon general election.[1] [2]
