Juan Almeida Bosque (February 17, 1927 – September 11, 2009) was a Cuban politician and one of the original commanders of the Cuban Revolution. After the 1959 revolution, he was a prominent figure in the Communist Party of Cuba; at the time of his death in 2009, he was a Vice-President of the Cuban Council of State and was its third ranking member. He received several decorations, and both national and international awards, including the title of "Hero of the Republic of Cuba" and the Order of Máximo Gómez.

Almeida was born in a poor area of Havana. He left school at the age of eleven and became a bricklayer. Whilst studying law at the University of Havana in 1952, he became close friends with the revolutionary Fidel Castro and in March of that year joined the Cuban Revolution. In 1953 he joined Fidel and his brother Raúl Castro in the assault on the Moncada Barracks in Santiago, and was arrested and imprisoned with the Castro brothers in the Isle of Pines Prison. During the amnesty of May 15, 1955, he was released and transferred to Mexico.
