The 2008 United States Senate election in Louisiana was held on November 4, 2008. This was the first time since the 1970s that Louisiana used primaries for federal races. Incumbent Democratic Senator Mary Landrieu won reelection to a third term, defeating Republican (and former Democrat) John Kennedy. Despite being forecast as one of the most vulnerable Senate Democrats during 2008, Landrieu won a comfortable victory of 6.4 percentage points. Landrieu had received praise and wide publicity for her advocacy after Hurricane Katrina, particularly during hearings regarding FEMA's response to the disaster. Kennedy had switched parties in 2007, just one year before the election, garnering allegations of being a political opportunist. Kennedy won the state's other U.S. Senate seat in 2016. , this is the last time that the Democrats won a U.S. Senate election in Louisiana.

Louisiana also elected a Republican senator in 2004 and President Bush carried the state twice, in 2004 with 58 percent of the vote.

After a continued backslide in support for the Democrats, Landrieu lost her seat by 12 points in 2014 to Bill Cassidy. Kennedy was later elected in the other Senate seat in 2016.
