The Bolivarian Circles (Spanish: Círculos bolivarianos) are a loosely-knit political and social organization of workers' councils in Venezuela originally begun by President Hugo Chávez in 2001. They are named in honor of Simón Bolívar, the leader who transformed most of South America from Spanish colonial outposts to the independent states now in place. Their significance to Venezuelan politics has trailed off significantly since 2003, as most circles have effectively disbanded. Since then the government has sponsored the creation of Community Planning Councils, which evolved into the Communal Councils.
Chávez organized these circles, which he cites as examples of grassroots and participatory democracy. The circles themselves were purportedly decentralized and made autonomous from any central government oversight. In 2001, however, Chávez authorized then-Vice President Diosdado Cabello to financially support them, which makes Chávez's opponents skeptical of any claims of autonomy.
Improvement projects undertaken by Bolivarian Circles include health, public transportation, and urban clean-ups. 
Prior to 2003, the circles took part in various protests against the political opposition. In January 2002, Bolivarian Circles were reported to have blocked the entrance of the newspaper office El Nacional for over an hour. Numerous journalists have been threatened, berated, and abused physically and verbally, particularly by people that identified with the Bolivarian Circles. Bolivian Circles also took part in demonstrations which partly became violent against the 2002 coup attempt.
According to a study by two Brigham Young University scholars, the Bolivarian circles embodied democratic values, in addition to "a charismatic mode of linkage to Chávez"; they performed valuable social work, but also often reinforced "clientelistic relations between Chávez and the voters, and they did not significantly enhance the level of pluralism in the broader civil society."
Pro-Chávez Bolivarian circles exist in other countries and are widespread in Europe, North America and Australia.
In 2001, Chávez swore in all official Bolivarian Circles at the first national reunion under the following oath, which was adapted from Bolívar's own oath on the hill of Monte Sacro in 1805:
I swear in front of you, for the God of my parents; I swear for them. I swear for my honor and for my motherland that I will not rest my arms nor my soul until we have broken, finally, the chains that oppress Venezuela as an inheritance of the powerful who destroyed the motherland. I swear that I will completely dedicate my work to the Bolivarian ideology, to the popular organization, to popular mobilization, to popular power, to never abandon the struggle; every day and every night that I have left with the Bolivarian circles in the Bolivarian web, in the Bolivarian current, in the Bolivarian forces and in the Revolutionary Bolivarian Movement 200 that today is born again after 19 years, by the will of the Venezuelan people. I swear that I will fight without rest for the defense of the revolution, even if I have to sacrifice my life, for the glory of Venezuela. I swear that we will consolidate forever the Bolivarian revolution and the motherland of our children. I swear.
