2006 United States House of Representatives election in Vermont

The 2006 United States House of Representatives election in Vermont was held on November 7, 2006 for representation of Vermont's at-large congressional district in the United States House of Representatives from January 3, 2007 to January 3, 2009.

Incumbent Congressman Bernie Sanders, an independent member of Congress who caucused with the Democrats, did not seek a ninth term in the House, instead running successfully for the United States Senate.

To replace Congressman Sanders, Democrat Peter Welch defeated Republican Martha Rainville by a surprisingly somewhat narrow margin (just under 10%) in staunchly-liberal Vermont. As of 2022, this is the last federal election in which a Republican received more than 33% of the vote.
