Vice Admiral Sir John Mennes (with several variant spellings), (1 March 1599 – 18 February 1671) was an English naval officer who went on to be Comptroller of the Navy.
He was also considered a wit.
His comic and satirical verses, written in correspondence with James Smith, were published in 1656.
He figures prominently in the Diary of Samuel Pepys; Pepys, who reported directly to Mennes at the Navy Office, thought him an incompetent civil servant but a delightful social companion.
