Bầu cử tổng thống Hoa Kỳ tại Nebraska năm 1984

The 1984 United States presidential election in Nebraska took place on November 6, 1984. All 50 states and the District of Columbia, were part of the 1984 United States presidential election. Voters chose five electors to the Electoral College, which selected the president and vice president of the United States.

Nebraska was won by incumbent United States President Ronald Reagan of California, who was running against former Vice President Walter Mondale of Minnesota. Reagan ran for a second time with former C.I.A. Director George H. W. Bush of Texas, and Mondale ran with Representative Geraldine Ferraro of New York, the first major female candidate for the vice presidency.

The presidential election of 1984 was a very partisan election for Nebraska, with over 99% of the electorate voting for either the Democratic or Republican parties, and only five parties formally appearing on the ballot. Reagan won a majority in all of Nebraska's counties, joining previous Republican nominees Theodore Roosevelt in 1904, Warren Harding in 1920, Dwight Eisenhower in 1952, Richard Nixon in 1972, and himself in 1980.

Nebraska weighed in for this election as 12% more Republican than the national average and with 70.55% of the popular vote, proved to be Reagan's third strongest state in the 1984 election after Utah and Idaho. Reagan won Nebraska by a powerful 42% margin. His 70.55% vote share in the state made it his third-best in the country, after Utah and Idaho. Nebraska continued its trend of voting in line with its sister free-soil and postbellum Great Plains states (North Dakota, South Dakota, and Kansas); the four last disagreed in a presidential election in 1916.

Reagan did well in population centers and rural areas alike, scoring almost two-thirds of the vote in the state's largest county, Douglas (home to Omaha), and getting over three-quarters of the vote in a majority of Nebraska's counties (58 of 93). Mondale's best county was Saline, at the time the strongest traditional stronghold for the Democratic Party in the state; the county had voted Democratic in every election from 1908 through 1976 save 1920, 1952, and 1972. Even here, however, Mondale failed to keep Reagan's margin to single digits.
