This is a list of electors (members of the Electoral College) who cast ballots to elect the President of the United States and Vice President of the United States in the 2004 presidential election. There are 538 electors from the 50 states and the District of Columbia. While every state except Nebraska and Maine chooses the electors by statewide vote, many states require that one elector be designated for each congressional district. Except where otherwise noted, such designations refer to the elector's residence in that district rather than election by the voters of the district.
