A list of alumni of St John's College, Oxford, former students of the college of the University of Oxford. The overwhelming maleness of this list is partially explained by the fact that for over 90% of its history (from its foundation in 1555 until 1979), women were barred from studying at St John's. The college maintains a growing list of profiles of prominent recent alumni on its website.
