The office of moderator of the General Assembly was the highest elected position in the Presbyterian Church in the United States of America (PCUSA). The moderator was responsible for presiding over the meeting of the General Assembly, which was held annually between 1789 and 1956. After the meeting, which lasted for about a week, the moderator served as an ambassador of the denomination throughout the remainder of the term. After completing the term, most former moderators took on the role of a church statesman.

Prior to the Old School–New School controversy The chart below shows the moderators and place of meetings from 1789 when the PCUSA was formed, until 1837, after which the denomination was divided into two factions by the Old School–New School Controversy until 1869.Proceedings of the 218th (2008) General Assembly, Presbyterian Church (U.S.A.), p. 1484 Number and year Place of meeting Moderator Online minutesConvened the 1st GA, 1789Philadelphia, Pennsylvania Rev.
