Oriel Square, formerly known as Canterbury Square. is a square in central Oxford, England, located south of the High Street. The name was changed after the Second World War at the request of Oriel College which maintained that the square had originally been known as Oriel Square.
The street is officially designated as part of the A420 due to the blockage of the High Street to normal traffic. To the north it continues as King Edward Street and to the east it continues as Merton Street.
The television crime series Inspector Morse used the square as a location in the episodes "The Dead of Jericho", "Last Seen Wearing", "The Ghost in the Machine", "Infernal Serpent", "Absolute Conviction", "Deadly Slumber" and "The Daughters of Cain".
