The 2008 United States Senate election in Iowa was held on November 4, 2008. Incumbent Senator Tom Harkin sought re-election to a fifth term in office.

Harkin defeated Reed in a landslide, winning 94 of Iowa's 99 counties. As of 2024 ^[update] , this is the last time that a Democrat has won a U.S. Senate election in Iowa.
