The chairman is the highest officer of an organized group such as a board, committee, or deliberative assembly. The person holding the office is typically elected or appointed by the members of the group. The chairman presides over meetings of the assembled group and conducts its business in an orderly fashion. When the group is not in session, the officer's duties often include acting as its head, its representative to the outside world and its spokesperson.

Other terms sometimes used for the office and its holder include presiding officer, president, moderator, chair, and convenor. The chairman of a parliamentary chamber is often called the speaker. Though chairwoman is sometimes used as a female counterpart to chairman, the terms chair and chairperson are sometimes used to avoid gendered titles altogether. The National Association of Parliamentarians does not approve using "chairperson". In the United States, the presiding officer of the "lower" house of a legislative body, such as the House of Representatives, is frequently titled the Speaker, while the "upper" house, such as the Senate, is commonly chaired by a President.
