The Bull and Mouth Inn was a coaching inn in the City of London that dated from before the Great Fire of London in 1666. It was located between Bull and Mouth Street (now Postman's Park) in the north and Angel Street in the south. It was once an important arrival and departure point for coaches from all over Britain, but particularly for the north of England and Scotland. It became the Queen's Hotel in 1830 but was demolished in 1887 or 1888 when new post office buildings were built in St Martin's Le Grand.
