William Kent was an English architect, landscape architect, painter and furniture designer of the early 18th century. He began his career as a painter, and became Principal Painter in Ordinary or court painter, but his real talent was for design in various media.

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.
