Oriel College () is a constituent college of the University of Oxford in Oxford, England. Located in Oriel Square, the college has the distinction of being the oldest royal foundation in Oxford (a title formerly claimed by University College, whose claim of being founded by King Alfred is no longer promoted). In recognition of this royal connection, the college has also been historically known as King's College and King's Hall. The reigning monarch of the United Kingdom (since 1952, Elizabeth II) is the official visitor of the college.
