# 1808–09 United States House of Representatives elections

The 1808–09 United States House of Representatives elections were held on various dates in various states between April 26, 1808, and May 5, 1809. Each state set its own date for its elections to the House of Representatives before the first session of the 11th United States Congress convened on May 22, 1809. They coincided with James Madison being elected as president. Elections were held for all 142 seats, representing 17 states.
Despite Madison's victory, voters in districts whose economies were driven by shipping or manufacturing rather than agriculture shifted to the Federalist Party mainly due to the unpopularity of the Embargo Act of 1807 and fears that Democratic-Republican Party policies could trigger a naval war with France or Britain. The politically dominant Democratic-Republicans won their smallest majority since the pivotal, realigning election of 1800.

## New York

Between the 1806 and 1808 elections, New York went through a redistricting that reduced the number of districts to 15 by creating two plural districts with two seats each. This brought the state's 17-seat delegation from a 15-2 ratio favoring Democratic-Republicans to a nearly-even 9–8 split in their favor.
