Cox & Hammond's Quay was a wharf located in the City of London, on the north bank of the River Thames a short distance downstream from London Bridge. It was originally two separate quays, Cox's Quay (also known as Cox's Key or Cock's Key) and Hammond's Quay, separated by Gaunt's Quay. On the landward side, the wharf was accessed via Lower Thames Street just behind the site of the church of St Botolph Billingsgate.
