Mississippi's six members of the Electoral College met Monday and all voted for Republican Mitt Romney, who carried the state in the presidential race.
Electors met around the country in a process that formalizes Democrat Barack Obama's re-election as president.
About two dozen people watched the brief process in a small room at the Mississippi Capitol, including Republican Gov. Phil Bryant.
The six electors were chosen at the state Republican convention in Jackson.
Alabama's members of the Electoral College cast the state's nine votes for Mitt Romney and Paul Ryan during a traditional ceremony at the state Capitol.
They were chosen by the state Republican Party because Romney carried Alabama.
