Last Mountain-Touchwood is a provincial electoral district for the Legislative Assembly of Saskatchewan, Canada.

Located in southern Saskatchewan, major communities in the district include the towns of Strasbourg, Ituna, Lemberg, Southey, and Balcarres.

Villages in the district include Punnichy, Kelliher, Lestock, Abernethy, Goodeve, Neudorf, and Lebret.

The district's southern and western boundaries have changed little since its creation, though the riding has been expanded eastward over the years.

The most significant expansion occurred before the 2003 general election, when the riding picked up the western half of the former Melville constituency upon its dissolution.
