The United States Senate elections of 1906 and 1907 were elections which had the Republican Party gain three seats in the United States Senate, expanding their majority to almost twice that of the opposing Democratic Party.

As these elections were prior to ratification of the seventeenth amendment, Senators were chosen by State legislatures.
