The 2008 United States presidential election in Alaska took place on November 4, 2008, as part of the nationwide presidential election held throughout all 50 states and the District of Columbia. Voters chose 3 electors, or representatives to the Electoral College, who voted for president and vice president.

Alaska was won by Republican nominee John McCain with a 21.53% margin of victory. Prior to the election, all 17 news organizations considered this a state McCain would win, or otherwise considered as a safe red state. Democratic nominee Barack Obama did, however, perform better in 2008 than Democratic nominee John Kerry did in 2004. This is the first election in which it participated in which it failed to support the same candidate as Virginia and Indiana, and the only time in which it did not do so for the latter.

The presence of the state's popular Governor, Sarah Palin, on the ticket as the Republican Party's vice presidential nominee appeared to help. The McCain–Palin ticket received just a slightly smaller percentage of Alaskan votes than did Bush–Cheney in 2004 despite the nation's swinging Democratic by 4.66% (48.27% to 52.93%). Polls from April until August indeed showed John McCain with a slim lead, with one poll taken in early August even showing Obama five points ahead. However, from when Sarah Palin was announced as McCain's running mate on August 29, polls showed John McCain consistently ahead. RealClearPolitics gave the state an average of 55.8% for McCain, compared to 41.3% for Obama.

In addition, McCain's 193,841 vote total is the most received by a presidential candidate in the state's history. As of the 2020 election, this is the last election in which Lake and Peninsula Borough, Northwest Arctic Borough, Aleutians West Census Area, Dillingham Census Area, and Yukon–Koyukuk Census Area voted for the Republican candidate.
