Thomas Brackett Reed Jr. was an American attorney, author, parliamentarian and Republican Party politician from Maine who served as the 32nd Speaker of the United States House of Representatives from 1889 to 1891 and 1895 to 1899. He represented Maine's 1st congressional district in the House from 1877 to 1899 and, prior to his time in Congress, represented Portland in the Maine legislature and served as Attorney General of Maine. In 1876, he was elected to represent Cumberland and York counties in the U.S. House and was re-elected for twelve consecutive terms.

The speaker of the United States House of Representatives, commonly known as the speaker of the House, is the presiding officer of the United States House of Representatives. The office was established in 1789 by Article I, Section II, of the U.S. Constitution. By custom and House rules, the speaker is the political and parliamentary leader of the House and is simultaneously its presiding officer, de facto leader of the body's majority party, and the institution's administrative head. Speakers also perform various other administrative and procedural functions. Given these several roles and responsibilities, the speaker usually does not personally preside over debates—that duty is instead delegated to members of the House from the majority party—nor regularly participate in floor debates.
