The title of Principal Painter in Ordinary to the King or Queen of England or, later, Great Britain, was awarded to a number of artists, nearly all mainly portraitists. It was different from the role of Serjeant Painter, and similar to the earlier role of "King's Painter". Other painters, for example Nicholas Hilliard had similar roles with different titles. "Principal Painter in Ordinary", first used for Sir Anthony van Dyck, became settled as the usual title with John Riley in 1689.
