The Colonial Land and Emigration Commission (CLEC), also known as the Colonial Land and Emigration Board, was a British government authority under the supervision of the Secretary of State for the Colonies that facilitated emigration within the British Empire. Established by a formal commission from Queen Victoria on 14 January 1840, the commission took over the responsibilities of two existing government offices, the South Australian Colonization Commission, and the Agent-General for Emigration.
