Cirque du Soleil is a Canadian entertainment company and the largest contemporary circus producer in the world. Located in the inner-city area of Saint-Michel, Montreal, it was founded in Baie-Saint-Paul on 16 June 1984 by former street performers Guy Laliberté and Gilles Ste-Croix.

Contemporary circus is a contested term in circus studies. In this article, it is used in contrast to the term 'traditional circus', combining with the genre elsewhere disambiguated as new circus or nouveau cirque. Many circus scholars prefer to separate these styles, as elaborated in circus. Contemporary circus, by this definition, is a genre of performing arts developed in the late 20th century in which a story, theme, mood or question is conveyed through traditional circus skills. For fans of animal performance in circus, this genre could arguably be found more akin to Variety as animals are rarely used, and traditional circus skills are blended with more choreographic, character-driven or mechanical approaches.
