The 1964 United States Senate election in Nebraska took place on November 3, 1964. Incumbent Republican Senator Roman Hruska ran for re-election. He was challenged by the Democratic nominee, Raymond W. Arndt, the personnel director at the Nebraska Public Power District. Despite Democratic President Lyndon B. Johnson's narrow victory over Barry Goldwater in Nebraska, Hruska won re-election in a landslide, winning 61% of the vote and winning every county in the state except for Saline County. This was the only race in the 1964 United States Senate elections in which the Republicans won by double digits.
