The chairperson (also chair, chairman, or chairwoman) is the presiding officer of an organized group such as a board, committee, or deliberative assembly. The person holding the office, who is typically elected or appointed by members of the group, presides over meetings of the group, and conducts the group's business in an orderly fashion.[1]

In some organizations, the chairperson is also known as president (or other title).[2][3] In others, where a board appoints a president (or other title), the two terms are used for distinct positions.
