The 1976 United States Senate elections was an election for the United States Senate that coincided with Democratic Jimmy Carter's presidential election and the United States Bicentennial celebration. Although almost half of the seats decided in this election changed parties, Carter's narrow victory did not provide coattails for the Democrats, and the balance of the chamber remained the same. This was the first election in which the Libertarian Party competed, running candidates in 9 of the 33 contested seats. There were no special elections in this election cycle.
