Sir Thomas Lake (1561 – 17 September 1630) was Secretary of State to James I of England. He was a Member of Parliament between 1593 and 1626.
Thomas Lake was baptised in Southampton on 11 October 1561, the son of Almeric Lake. He attended King Edward VI School, Southampton as a day boy. This meant that he did not have the level of French language tuition accorded to boarders by his Belgian schoolmaster Adrian Saravia. He did, however, gain excellent fluency in Latin.
He was an MP for Malmesbury in 1593, New Romney in 1601, Launceston in 1604, Middlesex in 1614 and Wootton Bassett in 1626.
He became the personal secretary of Sir Francis Walsingham, the Secretary of State, and was nicknamed ‘Swiftsure’ for his speed and accuracy. Walsingham brought Lake to the attention of Queen Elizabeth I and he was appointed Clerk of the Signet in 1600. As one of the Queen's favourites he travelled with her reading Latin texts to her on her progresses around the country.
On 28 March 1603, four days after the death of Elizabeth I of England the Privy Council sent him to Scotland with George Carew to inform James I of the current state of affairs and reiterate their urgent desire that the King should come to England. He was a protégé of the Howard family and became a favourite of James, who appointed him Secretary of the Latin Tongue and Keeper of the Records and then knighted him in 1603. He acted as the King's travelling secretary just as he had for Walsingham. His brother Arthur was one of the translators of the King James Bible appointed in 1604—the year that the reversion of Great Stanmore Manor in Middlesex was granted to Lake although it seems that he never took possession for the lordship remained in the name of the Burnell family until his son Thomas assumed possession in 1631. The adjoining manor of Little Stanmore contained the lands known as Canons, which Lake also acquired in 1604 and on which he built the grand brick mansion called Cannons to a design ascribed to John Thorpe
