The 2004 United States Senate election in Nevada was held on November 2, 2004. Incumbent Democratic U.S. Senator Harry Reid, the Senate Minority Whip, won re-election to a fourth term despite Republican President George W. Bush carrying the state in the concurrent presidential race.
Having only won re-election in 1998 by 428 votes, Harry Reid initially looked vulnerable given Nevada's position as a swing state for the presidential election. However the decision of top Republican recruit Jim Gibbons and other of other high profile potential challengers to pass on the race, left Reid appearing to be safe for a fourth term in the senate.
