# 1810–11 United States House of Representatives elections

The 1810–11 United States House of Representatives elections were held on various dates in various states between April 24, 1810, and August 2, 1811. Each state set its own date for its elections to the House of Representatives before the first session of the 12th United States Congress convened on November 4, 1811. They occurred during President James Madison's first term. Elections were held for all 142 seats, representing 17 states.
One newly elected Representative, Henry Clay, also was elected Speaker.
With the repeal of the Embargo Act of 1807, the economy improved. The opposition Federalists lost voter support and the Democratic-Republicans recovered a supermajority.

## New Hampshire

New Hampshire law required a candidate to receive votes from a majority of voters (10%). In the initial election, only two candidates won a majority, so a second election was held in April 1811 for the remaining three seats, after the congressional term began but before the Congress formally convened. The data from the source used give majorities to all the top five candidates, suggesting that the data are incomplete.
