Antasari Azhar (born 18 March 1953 in Pangkal Pinang on Bangka Island) is a former chairman of the Corruption Eradication Commission of Indonesia.

In 1999, Antasari joined the High State Prosecutor's Office, serving as chief investigator of the Special Crimes Sub-directorate (1999–2000).

It was as Chief of the South Jakarta State Prosecutor's Office (2000–2007) that he first gained widespread attention in the mass media.

In 2000, the Supreme Court sentenced former president Suharto's youngest son Tommy to 18 months in jail for corruption.

Hamzah by 41 votes in the election held by the 49 members of the Indonesian House of Representatives' (DPR) Commission III on legal affairs.
