Lanark was a provincial riding in Ontario, Canada, that was created for the 1934 election. In 1987 there was a minor redistribution and the riding was renamed to Lanark-Renfrew. It was abolished prior to the 1999 election. It was merged into the ridings of Renfrew—Nipissing—Pembroke and Lanark—Carleton.
