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 the 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.
