Philip Astley (8 January 1742 – 27 January 1814) is an English equestrian, circus owner, and inventor, regarded as being the "father of the modern circus".
The circus industry, as a presenter of an integrated entertainment experience that includes music, domesticated animals, acrobats, and clowns, traces its heritage to Astley's Amphitheatre, a riding school that Astley founds in London following the success of his invention of the circus ring in 1768.
