Congress of the Communist Party of Cuba in the context of "President of Cuba"

The Communist Party of Cuba (Spanish: Partido Comunista de Cuba, PCC) is the sole ruling party of Cuba. It was founded on 3 October 1965 as the successor to the United Party of the Cuban Socialist Revolution, which was in turn made up of the 26th of July Movement and Popular Socialist Party that seized power in Cuba after the 1959 Cuban Revolution. The party governs Cuba as an authoritarian one-party state where dissidence and political opposition are prohibited and repressed. The Cuban constitution ascribes the role of the party to be the "leading force of society and of the state."

The highest body within the PCC is the Party Congress, which convenes every five years. When the Congress is not in session, the Central Committee is the highest body. Because the Central Committee meets twice a year, most day-to-day duties and responsibilities are vested in the Politburo. Since April 2021, the First Secretary of the Central Committee has been Miguel Díaz-Canel, who has been serving as President of Cuba since 2018.

The First Secretary of the Central Committee of the Communist Party of Cuba is the top leader of Cuba. The first secretary is the highest office within the Communist Party of Cuba, which makes the officeholder the most powerful person in the Cuban party-state. In communist states the first or general secretary of a ruling communist party is typically the de facto leader of the country and a more powerful position than state offices such as President (head of state) or Prime Minister (head of government), when different individuals hold those positions.

The officeholder of the post of first secretary presides over the work of the Central Committee of the Communist Party of Cuba (PCC), which is designated as "the organised vanguard of the Cuban nation" and as "the superior driving force of society and the State" by Article 5 of Cuba's constitution. The PCC Central Committee, the Party's highest political-executive organ between convocations of the party congress, has the right to elect and dismiss the first secretary at one of its sessions. The first secretary is responsible for leading the work of the Secretariat, the Party's highest executive organ, and chairing the sessions of the Politburo, the Party's highest political organ. The current first secretary is Miguel Díaz-Canel, elected by the 1st Session of the 8th Central Committee on 19 April 2021, and he concurrently serves as president of Cuba.
