1806 and 1807 United States House of Representatives elections

The 1806 and 1807 United States House of Representatives elections were held at various dates in each state between April 29, 1806 (in New York) and August 4, 1807 (in Tennessee) during Thomas Jefferson's second term with the new Congress meeting on October 26, 1807.

The Democratic-Republicans continued to build on their huge supermajority. They were actually able to take over two more seats than they had in the previous Congress, which they controlled by a margin of better than three to one. Commitment to agrarian policy allowed the Democratic-Republicans to dominate rural districts, which represented the bulk of the nation. On the other hand, supporters of the Federalists, even in their traditional base of support in the urban centers of coastal New England, continued to lament the ineffectiveness of their party and its lack of electoral appeal.
