Kootenay was a provincial electoral district in the province of British Columbia, Canada, from 1871 to 1890. It was originally a two-member riding until the 1875 election; from 1878, it was a one-member seat until its partition for the 1890 election into East Kootenay and West Kootenay. For the 1966 election, the riding-name was re-established, but the area described was only the East Kootenay and included none of the West Kootenay.

The riding was partitioned for the 1894 election.
The riding-name was re-established in time for the 1966 election, but covered only the East Kootenay region rather than the entire Kootenays as had been the case in its first incarnation.
