Sir Philip Hoby (also Hobby or Hobbye) PC (1505 – 31 May 1558) was a 16th-century English Ambassador to the Holy Roman Empire and Flanders.

Hoby became a diplomat, largely thanks to the support he gave to the Protestant Reformation during the reign of King Henry VIII.

Hoby and Holbein departed the same night taking leave of the Duchess, (making a formal farewell), but not to the Lady Regent.

Antoinette guessed they had obtained the portrait of Anna of Lorraine there, and joked with her daughter, the Queen of Scotland, that soon either her sister or her cousin would become her neighbour by marrying Henry VIII.

Following the Siege of Boulogne, Hoby was knighted and received gifts of property, including some of the profits from the Dissolution of the Monasteries.

In 1548, he succeeded Bishop Thomas Thirlby as ambassador to the court of Charles V, Holy Roman Emperor.

[8] Sir Philip died at his house in Blackfriars, London and was buried in Bisham Church where there is a fine effigial monument to him and his brother.
