The 1976 United States Senate elections was an election for the United States Senate. Held on November 2, the 33 seats of Class 1 were contested in regular elections. They coincided with Democrat 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 Democratic Party. Each party flipped seven Senate seats, although, one of the seats flipped by Democrats was previously held by a Conservative.

This was the first election in which the Libertarian Party competed, running candidates in 9 of the 33 contested seats. As of 2024^[update] this is the first and so far only time both party leaders retired from the Senate in the same election cycle since the creation of the positions. This is the last time Democrats or any party won a 60% supermajority via direct elections (although Democrats briefly held one in the summer of 2009).

Scott listed personal reasons and several "well-qualified potential candidates" for the seat among the reasons of his decision to retire. Other reasons, including his support for Richard Nixon and accusations that he had illegally obtained contributions from Gulf Oil were alleged to have contributed to the decision.^[17]

Heinz was the victor in all but nine counties, defeating opponent William Green, who had a 300,000 vote advantage in his native Philadelphia area. Heinz and Green spend $2.5 million and $900,000, respectively, during the ten-month campaign. Much of the money Heinz spent on his campaign was his own, leading to accusations from Green that he was "buying the seat". Heinz replied to this by claiming that the spending was necessary to overcome the Democratic voter registration advantage.^[20]
