John Gellibrand Hubbard, 1st Baron Addington PC, was a City of London financier and a Conservative Party politician.

The governor of the Bank of England is the most senior position in the Bank of England. It is nominally a civil service post, but the appointment tends to be from within the bank, with the incumbent grooming their successor. The governor of the Bank of England is also chairman of the Monetary Policy Committee, with a major role in guiding national economic and monetary policy, and is therefore one of the most important public officials in the United Kingdom.
