Nebraska has had at least three congressional districts since 1883. The district's current configuration dates from 1963, when Nebraska lost a seat as a result of the 1960 United States Census. At that time, most of the old 3rd and 4th districts were merged to form the new 3rd district. It is one of the most Republican districts in the nation, as Democrats have only come close to winning it three times as currently drawn, in 1974, 1990, and 2006, all years where the incumbent was not running for reelection. Republican presidential and gubernatorial candidates routinely carry the district with margins of 40 percent or more, while Franklin D. Roosevelt in 1936 was the last Democratic presidential candidate to win a plurality within the current district boundaries.

Excepting historically Democratic Saline County on the district's eastern boundary and Dakota County which has only been within the district since 2013, the last Democrat to carry any county within the district at a presidential level was Jimmy Carter in 1976. Although the Nebraska Legislature is elected on a nonpartisan basis, all but two members representing significant portions of the district are known to be Republicans. With a Cook Partisan Voting Index (CPVI) of R+27, it is the most Republican congressional district outside the Southern United States. It is currently held by Republican Adrian Smith, who was first elected in 2006. The previous U.S. Representative, Tom Osborne, did not seek reelection in order to wage an unsuccessful campaign for the Republican nomination for Governor of Nebraska.
