Bank Junction is a major road junction in the City of London, the historic and financial centre of London, at which nine streets converge and where traffic is controlled by traffic lights and give-way lines. It is named after the nearby Bank of England. Directly underneath it is one of the ticket halls of Bank station, one of the busiest stations on the London Underground.

The Bank of England is the central bank of the United Kingdom and the model on which most modern central banks have been based. Established in 1694 to act as the English Government's banker and debt manager, and still one of the bankers for the Government of the United Kingdom, it is the world's eighth-oldest bank.
