Josias Priest (c. 1645 – 3 January 1735 in Chelsea, London) was an English dancer, dancing-master and choreographer.
In 1668, he was a dancing-master in Holborn, and in 1675 he moved to Leicester Fields to run a boarding school for gentlewomen.
In 1680 he started a similar school at Gorge's House in Chelsea, London which stood just behind what is now Lindsey Row, between.
Here Priest hosted operas, including John Blow's Venus and Adonis (1684) and Henry Purcell's Dido and Aeneas (1689).
It is widely believed that Priest choreographed dances for these and other semi-operas by Purcell, including Dioclesian, The Fairy-Queen, The Indian Queen, and King Arthur ; however, the evidence is not entirely conclusive.
