Yale-Lillooet was a provincial electoral district for the Legislative Assembly of British Columbia, Canada.
It first appeared in the 1966 General Election, when it superseded the older Lillooet riding, which was one of the province's original twelve ridings, as well as the equally old Yale riding, parts of which were also in Yale-Lillooet. Yale-Lillooet was last contested in the 2005 General Election; in 2009 it was largely replaced by Fraser-Nicola, with the Fraser Canyon portions in the southwest transferred to Chilliwack-Hope and the town of Keremeos in the extreme southeast transferred to Boundary-Similkameen.
The riding was largely rural and wilderness in character despite its proximity to the Lower Mainland, it spanned the Bridge River-Lillooet, Ashcroft-Thompson Canyon, Fraser Canyon, Nicola and Similkameen Districts.
Since creation its shape remained relatively unchanged despite some minor boundary adjustments, with (e.g.) Ashcroft-Cache Creek joining Cariboo South in some elections and the Similkameen area joined to one of the Okanagan ridings. Its core towns - Lillooet, Lytton, Yale, Boston Bar, Hope, Princeton, Merritt and Spences Bridge remained permanently in the riding until its demise.
