Similkameen was the name of a provincial electoral district in the Canadian province of British Columbia formed around the historic mining district of the same name. It made its first appearance on the hustings in the election of 1903. After the 1963 election, which was the occasion of this riding's last appearance, this electoral district was combined with Grand Forks-Greenwood to form Boundary-Similkameen for the 1966 election.
