Many details of Castro's private life, particularly involving his family members, are scarce, as such information is censored by state media.

Castro's first wife was Mirta Díaz-Balart, whom he married in October 1948, and together they had a son, Fidel Ángel "Fidelito" Castro Díaz-Balart, born in September 1949.
Díaz-Balart and Castro divorced in 1955, and she moved to Spain, although allegedly returned to Cuba in 2002 to live with Fidelito.
Fidelito grew up in Cuba; for a time, he ran Cuba's atomic-energy commission before being removed from the post by his father.
He took his own life in February 2018, over a year after his father's death.

While Fidel was married to Mirta, he had an affair with Natalia "Naty" Revuelta Clews, who gave birth to his daughter, Alina Fernández Revuelta.
Alina left Cuba in 1993, disguised as a Spanish tourist, and sought asylum in the U.S., from where she has criticized her father's policies.

Castro often engaged in one-night stands with women, some of whom were specially selected for him while visiting foreign allies.

Fidel had another daughter, Francisca Pupo (born 1953), the result of a one-night affair.
Pupo and her husband now live in Miami.

He also had another son, Jorge Ángel Castro (born in 1956), with María Laborde, a secret admirer he met shortly after he was out of prison.

Another son known as Ciro was also born in the early 1960s, the result of another brief fling, his existence confirmed by Celia Sánchez, Castro's closest confidante and also allegedly lover.

Fidel had five other sons by his second wife, Dalia Soto del Valle – Antonio, Alejandro, Alexis, Alexander "Alex", and Ángel Castro Soto del Valle.

His sister Juanita Castro has been living in the United States since the early 1960s, and was an opponent of her brother's regime.

While in power, Castro's two closest male friends were the former Mayor of Havana Pepín Naranjo and his own personal physician, René Vallejo.
From 1980 until his death in 1995, Naranjo headed Castro's team of advisers.
Castro also had a deep friendship with fellow revolutionary Celia Sánchez, who accompanied him almost everywhere during the 1960s, and controlled almost all access to the leader.
Castro was also a friend of the Colombian novelist Gabriel García Márquez.
