The 1804–05 United States Senate elections were held on various dates in various states. As these U.S. Senate elections were prior to the ratification of the Seventeenth Amendment in 1913, senators were chosen by state legislatures. Senators were elected over a wide range of time throughout 1804 and 1805, and a seat may have been filled months late or remained vacant due to legislative deadlock.{{cite web|url=https://www.archives.gov/milestone-documents/17th-amendment|title=17th Amendment to the U.S. Constitution: Direct Election of U.S. Senators (1913)|website=National Archives and Records Administration|date=February 8, 2022}} In these elections, terms were up for the senators in Class 2.

These elections expanded the Democratic-Republican Party's overwhelming control over the Senate. The Federalists went into the elections with such a small share of Senate seats (9 out of 34, or 27%) that even if they had won every election, they would have still remained a minority caucus.
