Sir John Fitzgerald was an Irish soldier of the seventeenth century, best known for serving as Governor of Tangier during the 1660s.
He commanded a regiment of Irish exiles in the service of Charles II, serving alongside the Spanish Army at the Battle of the Dunes in 1658.
The following year the Governor Andrew Rutherford, 1st Earl of Teviot amalgamated the two Irish regiment's under Fizgerald's command.
After Teviot's death during the Battle of Tangier against the Moors in 1664, he was temporarily replaced by Tobias Bridge.
During his time in Tangier, Fitzgerald fought a duel with a fellow officer Palmes Fairborne.
