United States elections, 1890

The 1890 United States elections occurred in the middle of Republican President Benjamin Harrison's term. Members of the 52nd United States Congress were chosen in this election. The Republicans suffered major losses due to the Panic of 1890 and the unpopularity of the McKinley Tariff. The Populist Party also emerged as an important third party.

Republicans suffered massive losses to Democrats in the House, and the Democrats took control of the chamber.

In the Senate, Democrats made minor gains, but Republicans kept control of the chamber. The Populists joined the Senate for the first time, electing two Senators.
