The Ministry of the Interior of the Republic of Cuba (Spanish: Ministerio del Interior de la República de Cuba), also known as MININT, is the Cuban government ministry which oversees the home affairs of Cuba. Its headquarter is in a building of Plaza de la Revolución, a central and famous square of Havana.

It was founded on June 6, 1961, replacing and expanding the old Ministry of the Interior (Ministerio de Gobernación), inherited by the Cuban Revolution from the previous governments.^[2]

The organs and structures that are part of the Minister fulfill functions of citizen security, and the establishment of the internal order.^[3] The MININT also includes various logistics agencies, force preparation, etc. In addition, it has commercial companies that provide security services as SEPSA (Specialized Protection Services, S.A.), SEISA or ACERPROT), which include chain stores selling to the population.

The Ministry oversees the functions of security and public order through the National Revolutionary Police Force (PNR)^[4] and the auxiliary body of the Committees for the Defense of the Revolution (CDR).

The MININT has its own teaching system, with several national schools (higher institutes) and schools in the provinces. In Havana, it has a polytechnic institute (named Instituto Superior del MININT Eliseo Reyes Rodríguez),^[4] for the training of media technicians in specialties related to criminal and police investigation lines.
