Sir John Houblon (13 March 1632 – 10 January 1712) was an English merchant and banker who served as the first governor of the Bank of England from 1694 to 1697. He also served as the Lord Mayor of London in 1695.

John Houblon was the third son of James Houblon, a London merchant, and his wife, Mary Du Quesne, daughter of Jean Du Quesne, the younger. He had nine brothers and three sisters. The Houblon family were Huguenots from Lille and he later became an elder in the French Protestant Church of London in Threadneedle Street.^[1]

His younger brother, Abraham Houblon, was also Bank of England Governor, from 1703 to 1705. A daughter of Abraham Houblon, Anne, was married to Henry Temple, later Viscount Palmerston, in 1703. His older brother, James, an influential merchant and Member of Parliament for the City of London, was also a director of the Bank of England.^[2] Four other of his brothers were prosperous merchants.^[3]

He became Sheriff of the City of London in 1689, an Alderman from 1689 to 1712, and Master of the Grocer's Company from 1690 to 1691. He was Lord Mayor in 1695.

He was a Lord Commissioner of the Admiralty from 1694 to 1699. It was during this time, from 1694 until 1697, that he served as inaugural governor of the Bank of England.^[4] He was again a Bank of England director from 1700, and a director of the New East India Company from 1700 to 1701.

He stood as a Parliamentary candidate for the City of London in 1701, but was defeated. Some sources state incorrectly that he was Member of Parliament for Bodmin.^[5]

He married Mary Jurin in 1660, who came from a Flemish Protestant family and they had five sons and six daughters, but only two sons survived their father.^[7] They lived in a magnificent house just off Threadneedle Street on the site later occupied by the Bank of England and he also acquired a country house at High Ongar in Essex.^[8]
