Circus skills are a group of disciplines that have been performed as entertainment in circus, sideshow, busking, or variety, vaudeville or music hall shows. Most circus skills are still being performed today. Many are also practiced by non-performers as a hobby.
Circus schools and instructors use various systems of categorization to group circus skills by type. Systems that have attempted to formally organize circus skills into pragmatic teaching groupings include the Gurevich system (the basis of the Russian Circus School's curriculum) and the Hovey Burgess system.
