Floyd James Fithian (November 3, 1928 – June 27, 2003) was an American educator and politician who served as a United States Representative from Indiana as a Democrat.

[6] While in the navy, Fithian was able to attend the University of Nebraska, where he received his Master of Arts in 1955 and, after teaching at a high school from 1956 to 1959, a Ph.D. in American history in 1964 from the same institution.

[10] During the 1970 midterm elections he served as Tippecanoe County coordinator for Philip A. Sprague's house campaign against incumbent Republican Earl Landgrebe and as president of the 2nd District Win-Dems organization.

[11][12] Landgrebe narrowly defeated Sprague in the general election by only 1,204 votes, but he was the first Democratic congressional nominee to win Tippecanoe County since the 1930s.

"[17] Landgrebe received a massive backlash from voters in his district for his support of Nixon and was resoundingly defeated in the 1974 election in a rematch with Fithian.

[20] In 1976 he sent a letter to Secretary of Defense Donald Rumsfeld asking him to demand former Air Force Undersecretary James W. Plummer's resignation as executive vice president of Lockheed Corporation due to the conflict of interests that would be created.

[24] On July 13, 1981, Fithian announced that he would retire from the House and would not seek reelection in either the 3rd, 5th, or 7th congressional districts or challenge Senator Richard Lugar and would instead run for Secretary of State.

On March 14, 2003, he joined seventy two other former congressmembers and signed a letter asking President George W. Bush and Prime Minister Tony Blair to give more time to the United Nations inspectors in Iraq.

[30] On June 27, 2003, Fithian died at his retirement home in Annandale, Virginia after suffering from Parkinson's disease and was interred in Arlington National Cemetery.
