List of United States senators from Vermont

Vermont was admitted to the Union on March 4, 1791. From the 1850s until well into the 20th century, Vermont was always represented by members of the Republican Party. Democrat Patrick Leahy (served 1975–2023) was Vermont's longest serving US senator. Its current members of the United States Senate are Independent Bernie Sanders (since 2007) and Democrat Peter Welch (since 2023). Both senators served in the United States House of Representatives immediately prior, where they represented Vermont's only House district.

Notes

1. Samuel S. Phelps was appointed by the governor during a recess of the state legislature, and the legislature later convened and adjourned a session without electing a senator to replace fill the vacancy. The Senate ruled that Phelps had lost his entitlement to sit when the legislature adjourned.^[8]
2. There has never been a Democratic Senator for Vermont's Class 1 Senate seat. Although Bernie Sanders ran for the Democratic nomination in 2016 and 2020, he has not joined the Democratic Party on his own Senate webpages.^[11]
