Speaker of the United States House of Representatives

The speaker of the United States House of Representatives, commonly known as the speaker of the House or House speaker, is the presiding officer of the United States House of Representatives, the lower chamber of the United States Congress. 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 many 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.

The Constitution does not explicitly require the speaker to be an incumbent member of the House of Representatives, although every speaker thus far has been, and as a member the speaker also represents their district and retains the right to vote. The speaker is second in the United States presidential line of succession, after the vice president and ahead of the president pro tempore of the Senate.

The 56th and current speaker of the House is Mike Johnson, a Republican from Louisiana.
