The 2012 United States presidential election in Idaho took place on November 6, 2012, as part of the 2012 United States presidential election in which all 50 states plus the District of Columbia participated. Idaho voters chose four electors to represent them in the Electoral College via a popular vote pitting incumbent Democratic President Barack Obama and his running mate, Vice President Joe Biden, against Republican challenger and former Massachusetts Governor Mitt Romney and his running mate, Congressman Paul Ryan. Prior to the election, 17 news organizations considered this a state Romney would win, or otherwise considered as a safe red state. Romney and Ryan carried Idaho with 64.09% of the popular vote to Obama's and Biden's 32.40%, thus winning the state's four electoral votes. Romney's victory in Idaho made it his fourth strongest state in the 2012 election after Utah, Wyoming and Oklahoma. He improved on McCain's performance in 2008, expanding his margin from 25.3% to 31.69% and flipping Teton County which had previously voted for Obama.
Caucuses
Democratic caucuses
President Obama ran unopposed in the caucuses. The District cast all 31 of its delegate votes at the 2012 Democratic National Convention for Obama.
Republican caucuses
The Republican caucuses took place on Super Tuesday, March 6, 2012. An advisory primary with no binding effect on delegates, scheduled to be held on Tuesday May 15, 2012, was cancelled by the Idaho Republican Party. Five candidates were on the ballot. In order of filing they are Ron Paul, Mitt Romney, Rick Santorum, Newt Gingrich, and Buddy Roemer. Although Roemer had withdrawn from the Republican race before the Idaho caucus, he still appeared on the ballot.
Idaho has 32 delegates to the Republican national convention, of which 3 are RNC and 29 are AL. The 3 RNC delegates pledged to go with the results of the Boise Straw Poll. The delegates will be determined by the caucuses results, based on a two-step approach. First, the delegates are primarily awarded winner-take-all by county after a series of votes in which candidates are successively removed from the ballot. Then, if a candidate receives half or more of the county delegates, they will receive all the 32 delegates; if not, the delegates will be split proportionately according to the number of county delegates. Mitt Romney won 61% of the vote, thanks to a large majority of support (80-90% in most counties) in majority Mormon southeastern Idaho, rendering it a winner-take-all contest. Santorum and Paul split the Panhandle, winning five counties each, but came away empty in the delegate count.

Notes
- That these totals reflect the final caucus ballots in each county; where only two candidates have votes totaled, this was likely from other candidates being eliminated in previous rounds of voting. Where all candidates have at least one vote, only one ballot was necessary, since the winning candidate had a majority of votes in that county.
- Vote totals for Buddy Roemer, who had formally withdrawn from the Republican race before the caucus, are not provided.
