Abraham "Ditto" Pascual Sarmiento Jr. (June 5, 1950 – November 11, 1977) was a Filipino student journalist who gained prominence as an early and visible critic of the martial law regime of dictator Ferdinand Marcos.

His father, Abraham Sarmiento Sr., was a well-known lawyer and close friend of President Diosdado Macapagal who would be appointed an Associate Justice of the Supreme Court of the Philippines years after his son's death.

[4] In 1967, Ditto enrolled at the University of the Philippines in Diliman where he joined the Alpha Phi Beta fraternity, the Greek letter organization of his father.

[1] Philippine newspapers and other mass media outlets had been closed upon the declaration of martial law, with only those sympathetic to the Marcos government being allowed to re-open.

[1] Against this backdrop, the Collegian under Ditto's leadership began to publish articles and editorials criticizing martial law and calling for the restoration of democracy.

")[9][10] Ditto was said not to possess radical or leftist beliefs himself but was spurred into action by a sense of justice and fair play.

They were released shortly, but not before they were brought before Defense Minister Juan Ponce Enrile, who personally expressed displeasure over the editorial.

[8] The following month, Ditto wrote an editorial for the Collegian entitled "Where Do We Go from Here" which criticized Marcos's New Society and urged public debate about martial law.

"[15] Ditto's father interceded with Deputy Defense Minister Carmelo Barbero to obtain medical attention for his son.

On November 11, 1977, a little over a year after his release, the 27-year-old Ditto was found dead on his bedroom floor after suffering a heart attack.

[17] After Ditto's death, his father intensified his participation in the political opposition against the Marcos government, and would himself be detained in 1979 after publishing a book critical of the regime.
