Coldharbour, also spelled Cold Harbour, Cold Harborough, Cold Herbergh, Cold Herberge, and Cold Inn, were two London neighbouring estates in the since dissolved parishes of All-Hallows-the-Less and All-Hallows-the-Great, in today's Dowgate Ward of the City of London. From the 13th century to the mid-17th century Coldharbour occupied the area between Upper Thames Street and the Thames to the east of Cannon Street station. It was destroyed in the Great Fire of 1666. One of the estates was used by the Dukes of Exeter and briefly as a college of heralds.
