Philippine–American War Mariano Núñez Llanera (born Mariano Llanera y Núñez; November 9, 1855 – September 19, 1942) was a Filipino revolutionary general from Cabiao, Nueva Ecija who fought in his aforementioned home province, and also in the neighboring provinces of Bulacan, Tarlac, and Pampanga.

He is considered one of the "three Fathers" (the main instigators/ commanders) of the Cry of Nueva Ecija, along with Pantaleon Valmonte and Manuel Tinio.

Among the leaders were Mariano and his son Eduardo Llanera, Mamerto Natividad, Alipio Tecson and Manuel Tinio.

Despite having only 100 rifles, the rebels furiously held siege the Spaniards in the Casa Tribunal, the arsenal, and other government buildings.

The Spanish authorities hastily organized a company of 200 armed civilian Spaniards and mercenaries the following day and attacked the overconfident insurgents, driving the latter away from the government center.

On February 23, 1899, Llanera and his troops were with Luna's forces when the latter staged a counterattack in Caloocan to prevent the Americans from invading further north.

He was deported to Guam on January 16, 1901 with Artemio Ricarte and 30 more military officers of the Revolution considered Irreconcilables by the Americans.
