Senior Man is a position held in some collegiate universities by the head of a college's JCR (the undergraduate student body). It is the equivalent of 'President'. The Senior Man acts as the chief representative of the student body, as a figurehead for the JCR and as an elected official. He or she is also responsible for leading the JCR's executive council.
Although terminology refers to the position as a Senior 'Man', a woman may also fill this role. This reflects the history of these colleges, which were originally founded as single sex male-only institutions.
The position of Senior Man is currently in use at three colleges of Durham University:
- University College 
- Hatfield College 
- St Chad's College, (the term 'Senior Woman' is also used in this college)
