Frederick Huntington Gillett (/dʒɪˈlɛt/; October 16, 1851 – July 31, 1935) was an American politician who served as the 42nd Speaker of the United States House of Representatives from 1919 to 1925 and as a U.S.

He graduated from Amherst College, where he was a member of the Alpha Delta Phi fraternity, in 1874 and Harvard Law School in 1877.

Gillett was nominated by the Republican caucus for Speaker of the House in the upcoming 66th United States Congress.

[6] Gillett was expected to exercise less control than his predecessor, since he was characterized by one reporter as someone who did not drink coffee in the morning "for fear it would keep him awake all day".

In 1923, votes cast by the Progressive wing of the GOP resulted in multiple ballots as no Speaker candidate gained a majority.

On the ninth ballot, after the Republican leadership agreed to Progressive procedural reforms, Gillet was eventually elected.

[18] In 1934, he published a biography of George Frisbie Hoar, an earlier congressman and senator from Massachusetts, and his wife's father-in-law from her previous marriage.
