Bouteflika suffered a stroke in 2013 that badly weakened him.
Algeria's former president Abdelaziz Bouteflika has died aged 84, state television announced on Friday.
Bouteflika fought for independence from France, reconciled his conflict-ravaged nation, and was then ousted amid pro-democracy protests in 2019 after two decades in power.
The report did not give the cause of death or information about funeral arrangements.
Bouteflika had suffered a stroke in 2013 that badly weakened him.
Concerns about his state of health were kept secret from the Algerian public and helped fuel public frustration with his 20-year rule.
Mass public protests by the Hirak movement led to his departure.
An astute political chameleon, Bouteflika had been known as a wily survivor ever since he fought for independence from colonial ruler France in the 1950s and 1960s.
