(also known as Josias Preist, possibly Joseph Priest; died January 1735 in Chelsea parish, England), English dancer, dancing master, and choreographer. Members of the Priest family are among the most prominent of the Restoration dancing masters. Josiah was well known for productions of works by composers John Blow and Henry Purcell at his school in Chelsea during the 1680s. A Joseph Priest (also referred to in documentation as John and may or may not be the same person as Josiah), took part in court and theater productions from at least 1667 when he appeared with Moll Davies in the masque for the final act of John Dryden's Sir Martin Mar-all at Lincoln's Inn Fields theater.
