Corruption in Cuba is a serious concern. Cuba has suffered from widespread corruption since the establishment of the Republic of Cuba in 1902. The book Corruption in Cuba states that public ownership resulted in "a lack of identifiable ownership and widespread misuse and theft of state resources... when given opportunity, few citizens hesitate to steal from the government." Furthermore, the complex relationship between governmental and economic institutions makes them especially "prone to corruption."

The question of what causes corruption in Cuba presently and historically continues to be discussed and debated by scholars. There are the traditional principles of governance that it inherited from Spain, which was known as a notoriously corrupt regime in its interactions with the New World. Jules R. Benjamin suggests that Cuba's corrupt politics were a product of the colonial heritage of Cuban politics and the financial aid provided by the United States that favoured international sugar prices in the late 19th and early 20th centuries. Following the Second World War, the level of corruption in Cuba, among many other Latin American and Caribbean countries, was said to have risen significantly. Some scholars, such as Eduardo Sáenz Rovner, attribute this to North America's increased involvement in Cuba after the First World War, which isolated Cuban workers. Cubans were excluded from a large sector of the economy and were unable to participate in managerial roles that were taken over by United States employers. Along similar lines, Louis A. Pérez has written that “World War Two created new opportunities for Cuban economic development, few of which, however, were fully realized. Funds were used irrationally. Corruption and graft increased and contributed in no small part to missed opportunities, but so did mismanagement and miscalculation.”

Transparency International's 2025 Corruption Perceptions Index gave Cuba a score of 40 on a scale from 0 ("highly corrupt") to 100 ("very clean"). When ranked by score, Cuba ranked 84th among the 182 countries in the Index, where the country ranked first is perceived to have the most honest public sector. For comparison with regional scores, the best score among the countries of the Americas was 75, the average score was 42 and the worst score was 10. For comparison with worldwide scores, the best score was 89 (ranked 1), the average score was 42, and the worst score was 9 (ranked 181, in a two-way tie).

History

Pre-Revolution

In the decades following the United States' invasion of Cuba in 1898, and formal independence from the U.S. on 20 May 1902, Cuba experienced a period of significant instability, enduring a number of revolts, coups and a period of U.S. military occupation. The Republic of Cuba largely became characterized by a deeply ingrained tradition of corruption where political participation resulted in opportunities for elites to engage in wealth accumulation. Cuba's first presidential period under Don Tomás Estrada Palma from 1902 to 1906 was considered to uphold the best standards of administrative integrity in the history of the Republic of Cuba. However, a United States intervention in 1906 resulted in Charles Edward Magoon, an American diplomat, taking over the government until 1909. Although Magoon's government did not condone corrupt practices, there is debate as to how much was done to stop what was widespread especially with the surge of American money coming into the small country. Hugh Thomas suggests that while Magoon disapproved of corrupt practices, corruption persisted under his administration and he undermined the autonomy of the judiciary and their court decisions. On 29 January 1909, the sovereign government of Cuba was restored, and José Miguel Gómez became president. No explicit evidence of Magoon's corruption ever surfaced, but his parting gesture of issuing lucrative Cuban contracts to U.S. firms was a continued point of contention. Cuba's subsequent president, José Miguel Gómez, was the first to become involved in pervasive corruption and government corruption scandals. These scandals involved bribes that were allegedly paid to Cuban officials and legislators under a contract to search the Havana harbour, as well as the payment of fees to government associates and high-level officials. Gómez's successor, Mario García Menocal, wanted to put an end to the corruption scandals and claimed to be committed to administrative integrity as he ran on a slogan of "honesty, peace and work". Despite his intentions, corruption actually intensified under his government from 1913 to 1921. Instances of fraud became more common while private actors and contractors frequently colluded with public officials and legislators. Charles Edward Chapman attributes the increase of corruption to the sugar boom that occurred in Cuba under the Menocal administration. Furthermore, the advent of World War One enabled the Cuban government to manipulate sugar prices, the sales of exports and import permits. While in office, García Menocal hosted his college fraternity, in the 1920 Delta Kappa Epsilon National Convention, the first international fraternity conference outside the US, which took place in Cuba. He was responsible for creating the Cuban Peso; until his presidency Cuba used both the Spanish Real and US Dollar. President Menocal left the Cuban national treasury in overdraft and therefore in precarious financial situation. Menocal supposedly spent $800 million during his 8 years in office and left a floating debt of $40 million.

Alfredo Zayas succeeded Menocal from 1921 to 1925 and engaged in what Calixto Masó refers to as the "maximum expression of administrative corruption". Both petty and grand corruption spread to nearly all aspects of public life and the Cuban administration became largely characterized by nepotism as Zayas relied on friends and relatives to illegally gain greater access to wealth. Gerardo Machado succeeded Zayas from 1925 to 1933, and entered the presidency with widespread popularity and support from the major political parties. However, his support declined over time. Due to Zayas' previous policies, Gerardo Machado aimed to diminish corruption and improve the public sector's performance through an "honest administration", which had been referred to as moralización, from 1925 to 1933. While he was successfully able to reduce the amounts of low level and petty corruption, grand corruption still largely persisted. Machado embarked on development projects that enabled the persistence of grand corruption through inflated costs and the creation of "large margins" that enabled public officials to appropriate money illegally. Under his government, opportunities for corruption became concentrated into fewer hands with "centralized government purchasing procedures" and the collection of bribes among a smaller number of bureaucrats and administrators. Through the development of real estate infrastructures and the growth of Cuba's tourism industry, Machado's administration was able to use insider information to profit from private sector business deals. Many people objected to his running again for re-election in 1928, as his victory violated his promise to serve for only one term. As protests and rebellions became more strident, his administration curtailed free speech and used repressive police tactics against opponents. Machado unleashed a wave of violence against his critics, and there were numerous murders and assassinations committed by the police and army under Machado's administration. The extent of his involvement in these is disputed, though Russell Porter makes the claim that Machado confessed to being involved. Though the extent of Machado's participation in such violent acts is unknown, he has since been described as a dictator. In May 1933, Machado was forced out as newly appointed US ambassador Sumner Welles arrived in Cuba and initiated negotiation with the opposition groups for a government to succeed Machado's. A provisional government headed by Carlos Manuel de Céspedes y Quesada (son of Cuban independence hero Carlos Manuel de Céspedes) and including members of the ABC was brokered; it took power on 12 August 1933 amidst a general strike in Havana.

Carlos Manuel de Céspedes y Quesada subsequently was offered the position of President by ambassador Sumner Welles. He took office on 12 August 1933, and Welles proposed that "general elections may be held approximately 3 months from now so that Cuba may once more have a constitutional government in the real sense of the word." Céspedes agreed, and declared that a general election would be held on 24 February 1934, for a new presidential term to begin on 20 May 1934. However, on 4-5 September 1933, the Sergeants' Revolt took place while Céspedes was in Matanzas and Santa Clara after a hurricane had ravaged those regions. The junta of officers led by Sergeant Fulgencio Batista and students proclaimed that it had taken power in order to fulfill the aims of the revolution; it briefly described a program which included economic restructuring, punishment of wrongdoers, recognition of public debts, creation of courts, political reorganization, and any other actions necessary to construct a new Cuba based on justice and democracy. Only five days after the coup, Batista and the Student Directory promoted Ramón Grau to the role of President. The ensuing One Hundred Days Government issued a number of reformist declarations but never gained diplomatic recognition from the US; it was overthrown in January 1934 under pressure from Batista and the US ambassador. Grau was replaced by Carlos Mendieta, and within five days the U.S. recognized Cuba's new government. The corruption was not curtailed under Mendieta and he resigned in 1935 after unrest continued, and their followed a number of interim and weak presidents under the guidance of Batista and the US. Batista, supported by the Democratic Socialist Coalition which included Julio Antonio Mella's Communist Party, defeated Grau in the first presidential election under the new Cuban constitution in the 1940 election, and served a four-year term as President of Cuba. Batista was endorsed by the original Communist Party of Cuba (later known as the Popular Socialist Party), which at the time had little significance and no probability of an electoral victory. This support was primarily due to Batista's labor laws and his support for labor unions, with which the Communists had close ties. In fact, Communists attacked the anti-Batista opposition, saying Grau and others were "fascists" and "reactionaries".
