The '''1804–05 United States House of Representatives elections''' were held on various dates in various states between April 24, 1804 (in [[New York (state)|New York]]), and August 5, 1805 (in [[Tennessee]]). Each state set its own date for its elections to the [[United States House of Representatives|House of Representatives]] before the first session of the [[9th United States Congress]] convened on December 2, 1805. The elections occurred at the same time as [[President of the United States|President]] [[Thomas Jefferson]]'s re-election. Elections were held for all 142 seats, representing 17 states.

Under Jefferson's popular administration, his party continued to gain seats in the House. Territorial acquisitions from the [[Louisiana Purchase]] and economic expansion gave voters a positive view of the [[Democratic-Republicans]], whose majority, already commanding in the [[8th United States Congress|8th Congress]], now surpassed three-quarters of the total membership. Following this election, [[Federalist Party|Federalists]] were able to secure few seats outside of [[New England]] and party legitimacy deteriorated as political thought turned away from Federalist ideals perceived to be elitist and anti-democratic.

New York held elections for the 9th Congress on April 24–26, 1804.  For this year and the next election year, the 2nd and 3rd districts had combined returns, effectively a plural district with 2 seats, though still numbered as separate districts.  At the time, District 2 consisted of only part of [[New York County, New York|New York County]], while District 3 consisted of the remainder of New York County plus [[Kings County, New York|Kings]] and [[Richmond County, New York|Richmond Counties]].  By consolidating the two, it ensured that New York County would be combined into a single district.

== Non-voting delegates ==
{{See also|Delegate (United States Congress)}}

There were three territories with [[Delegate (United States Congress)|non-voting delegates]] in the 9th Congress, one of which (the [[Orleans Territory]]) did not send its first representative [[1806–07 United States House of Representatives elections#Non-voting delegates (9th Congress)|until 1806]].  The delegates were elected by the territorial legislatures, votes here are the number of members of the territorial legislatures voting for each candidate.

In the [[Mississippi Territory]], the territorial legislature was locked.  The first vote given above was on the 7th ballot, after which point the territorial legislature adjourned, the second vote was at a later session of the territorial legislature.
