Kaslo-Slocan was the name of a provincial electoral district in the Canadian province of British Columbia centred on the town of Kaslo on Kootenay Lake as well as the mining towns of the "Silvery Slocan". The riding first appeared in the 1924 election as the result of a merger of the former ridings of Kaslo and Slocan, and lasted until the 1963 election.
