President is a title held by many leaders of organizations, companies, trade unions, universities, and countries. Etymologically, a "president" is one who presides, who sits in leadership (from Latin pre- "before" + sedere "to sit"; giving the term praeses). Originally, the term referred to the presiding officer of a ceremony or meeting (i.e., chairman), but today it most commonly refers to an official. Among other things, president today is a common title for the heads of state of most republics, whether popularly elected, chosen by the legislature or by a special electoral college. It is also often adopted by dictators.

As an English word, the term was originally used to refer to the presiding officer of a committee or governing body in Great Britain. Early examples are the President of the Exchequer ("presidentis" in the original Latin, from the Dialogue concerning the Exchequer, 1179), the presidents of the universities of Oxford and Cambridge (from 1464), and the founding President of the Royal Society (William Brouncker, 1660).
