The Chatham Undergraduate Student Government (CSG) is the governing structure that provides an orderly method of government that is representative of all undergraduate students and advocates for the concerns, interests, needs, and welfare of the undergraduate student body at Chatham University.

Chatham Student Government functions under the decisions of student-elected officials and the guidance of administrative members of the University. These students who are elected will participate in three kinds of meetings: Senate, Class, and Committee.

Senate Meetings:
Senate meetings are held every Thursday during Chapel hour from 11:30 am to 12:30 pm. There, every member of CSG is able to represent their constituents through proposing and voting on resolutions and bills and discussing issues on campus. Sometimes guests from specific offices on campus will be invited to discuss these issues, like Public Safety or IT. Anyone on campus can attend a Senate meeting to see what topics are being discussed as well as voice their own opinions during the Open Forum.
