The 2006 United States Senate election in Indiana was held November 7, 2006. Incumbent Republican United States Senator Richard Lugar was re-elected to his sixth six-year term with 87.3% of the vote. He did not have a Democratic opponent and only faced opposition from a Libertarian candidate; this was the only U.S. Senate race in 2006 in which Democrats did not field a candidate.
This would be the last successful race of Lugar's decades long political career. This is also the last time that Lake, Marion, and Monroe counties have voted for a Republican candidate for Senate.
As of 2024 this is the last election where an incumbent Senator won re-election in the Class 1 seat.
