Donato Mármol (February 14, 1843 – June 26, 1870) was a Cuban revolutionary and general who played a key role in the Ten Years' War in Cuba.

[1] His father, a Venezuelan native and captain in the Spanish Army, moved with his family to Santiago de Cuba, where Donato finished his education.

[2] Mármol was involved in early revolutionary meetings, including one led by Carlos Manuel de Céspedes in September 1868, where he acted as the leader of Jiguaní.

[13] Revolutionary discord peaked with Mármol's self-proclamation as Dictator, but Francisco Vicente Aguilera's intervention at a meeting in Tacajó on January 29, 1869, stabilized the movement.

[15] Donato Mármol died from cerebral fever on June 26, 1870, in the Baraguá camp, and was buried at the San Felipe Estate near the Cauto River in Palma Soriano.
