Trade commissioner is the title of a government official whose primary duties are to promote international trade agreements and export trade programs on behalf of a national or regional government authority. Such envoys are normally posted abroad, often being permanently resident in the country or region to which they have been assigned, but in some cases are locally engaged employees. If assigned by an authority or organization lacking sovereignty, or if a local employee, a trade commissioner may not enjoy diplomatic status. The title Trade Commissioner is also used by some international organizations for the senior official responsible for trade.
