The Boar's Head Inn is the name of several former and current taverns in London, most famously a tavern in Eastcheap that is supposedly the meeting place of Sir John Falstaff, Prince Hal and other characters in Shakespeare's Henry IV plays. An earlier tavern in Southwark used the same name, and an inn of the name in Whitechapel was used as a theatre.
A number of other taverns and inns have since used the name, typically with reference to Shakespeare.
