The posts of shadow United States senator and shadow United States representative are held by elected or appointed government officials from subnational polities of the United States that lack congressional vote. While these officials are not seated in either chamber of Congress, they seek recognition for their subnational polity, up to full statehood. This would enfranchise them with full voting rights on the floor of the U.S. House and Senate, alongside existing states. As of 2021[update], only the District of Columbia and Puerto Rico currently have authorized shadow delegations to Congress.
This is distinct from shadow delegates, who are elected or appointed from subnational polities of the United States to seek non-voting participation in the House. As of 2024, only the Cherokee Nation and the United Keetoowah Band of Cherokee Indians have elected shadow delegates.
