Zahirul Islam Abbasi (Urdu: ﻇﻬﻴﺮ ﺍﻹﺳﻼﻡ ﻋﺑﺎﺳﻰ; 12 January 1943 – 30 July 2009) was a major general of the Pakistan Army.

Serving in the Siachen region of the disputed territory of Kashmir, Abbasi planned and executed assaults on Indian Army posts.

Abbasi was sentenced to 7 years imprisonment for being party to an attempted coup d'état against the civilian government of Benazir Bhutto in 1995 while he was still a serving major general.

Abbasi remained a part of the military establishment as long as he was in service with no links to any political or religious groups as per the tradition of the army.

At the time of the attempted coup, Abbasi held the post of director-general of Infantry Corps at the Army General Headquarters GHQ – a staff position where he did not command any troops.

The coup plotters were arrested, and following a court-martial, Abbasi was moved to the civilian central prison at Haripur in Khyber Pakhtunkhwa.

With his military career over, Abbasi moved to organise a political party with the aim of creating awareness and establishing the rule of Islamic law through constitutional change.
