Dario Fo (Italian pronunciation: ['da:rjo 'fo]; 24 March 1926 - 13 October 2016) was an Italian actor-playwright, comedian, singer, theatre director, stage designer, songwriter, painter, political campaigner for the Italian left-wing and the recipient of the 1997 Nobel Prize in Literature. In his time he was "arguably the most widely performed contemporary playwright in world theatre". Much of his dramatic work depends on improvisation and comprises the recovery of "illegitimate" forms of theatre, such as those performed by giullari (medieval strolling players) and, more famously, the ancient Italian style of commedia dell'arte. His plays have been translated into 30 languages and performed across the world, including in Argentina, Chile, Iran, the Netherlands, Poland, Romania, South Africa, South Korea, Spain, Sri Lanka  Sweden, the UK and Yugoslavia.

In 2001, Fo became Satrap of the College de 'Pataphysique. In 2004, Forza Italia senator Marcello Dell'Utri, on trial at the time for money laundering, sued Fo over references to him in his latest play. Fo was disgusted: "I have been doing satire for 40 years. It is paradox. It is grotesque." The play, titled The Two-Headed Anomaly and first performed in 2003, also poked fun at the shortness of then prime minister Silvio Berlusconi, had him strapped to a chair and given electric shock treatment and portrayed Vladimir Putin being shot dead by Chechen rebels while visiting Berlusconi's luxury villa in Sicily. The title refers to the subsequent transplanting of Putin's brain into Berlusconi's head, and the play was performed amid debate over Berlusconi's business and political interests and media censorship, with RAI having barred Italian satirists Sabina Guzzanti and Paolo Rossi from its television channels. Fo spoke of receiving threats from politicians if he performed it.  In 2005, Fo revealed plans to run for Mayor of Milan, the most economically important city in Italy, the following year. He said it was part of his ongoing fight to rid Milan of Berlusconi's political colleague Gabriele Albertini, the incumbent mayor. Ostracised by Italian television (both state--RAI having shunted his latest show off to a graveyard slot--and commercial--three quarters owned by Fo's long-time adversary Berlusconi), Fo instead elected to campaign on stage. Under the slogan "I am not a moderate", he opposed the centre-right administration's plans to demolish parts of the city centre and vowed to chase out those "money-grabbing bastards who have run this city for decades." Securing 23.4% of the vote in the primary election of centre-left The Union in January 2006, he was ultimately unsuccessful, finishing second to Milan's former police chief Bruno Ferrante.  Throughout the early 21st century until his death in 2016, Fo remained an active participant and campaigner on various political, social and cultural issues. He questioned the official accounts of the September 11 attacks and the collapse of the World Trade Center buildings in the film, Zero: An Investigation into 9/11. In 2008, he was among the signatories of an open letter to la Repubblica which called on the state to protect Roberto Saviano, whose life was under threat after exposing the clandestine activities of the Camorra in his 2006 book Gomorrah. Ahead of the 2013 Italian general election, Fo explained that the most recent targets of his satire included: "The banks mostly, and the big entrepreneurs. All those who hold the reins 'the show within a show', i.e. those who - through the media, television and in other ways - make every effort to ensure that the people accept the conditions they find themselves in."
