Kevin Owen McCarthy is an American politician who served as the 55th speaker of the United States House of Representatives from January to October 2023. A member of the Republican Party, he was the U.S. Representative for California's 20th congressional district from 2007 until his resignation in 2023.

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.
