The Communist Refoundation Party is a communist political party in Italy that emerged from a split of the Italian Communist Party (PCI) in 1991. The party's secretary is Maurizio Acerbo, who replaced Paolo Ferrero in 2017. Armando Cossutta was the party's founder, while Fausto Bertinotti its longest-serving leader (1994–2008). The latter transformed the PRC from a traditional communist party into a collection of radical social movements.

The Italian Communist Party was a communist and democratic socialist political party in Italy. It was founded in Livorno as the Communist Party of Italy on 21 January 1921, when it seceded from the Italian Socialist Party (PSI), under the leadership of Amadeo Bordiga, Antonio Gramsci, and Nicola Bombacci. Outlawed during the Italian fascist regime, the party continued to operate underground and played a major role in the Italian resistance movement. The party's peaceful and national road to socialism, or the "Italian Road to Socialism", the realisation of the communist project through democracy, repudiating the use of violence and applying the Constitution of Italy in all its parts, a strategy inaugurated under Palmiro Togliatti but that some date back to Gramsci, would become the leitmotif of the party's history.
