The Attorney General's Office of the Republic of Indonesia (Indonesian: Kejaksaan Agung Republik Indonesia, abbreviated as Kejagung) is the competent authority to advise the Government of Indonesia on matters of law. It serves as the central organization for the Indonesian Public Prosecution Service (Kejaksaan Republik Indonesia). The Attorney General's Office is seated in the national capital Jakarta.

The Office is headed by the Attorney General of Indonesia, who has the authority to represent the government at the Supreme Court of Indonesia and is a Cabinet-level official. The Office is not part of any justice portfolio or the Judiciary, however, as the cabinet has its own Ministry of Law (Kementerian Hukum) with a separate Minister of Law (Menteri Hukum) that focuses on more technical matters and regulatory role making rather than executing the Supreme Court's order.

The Attorney-General also functions as a Solicitor General. Thus, the Attorney-General can represent the Government in the Supreme Court. The Attorney-General has the power to indict and prosecute alleged criminals. The term of office of the Attorney General was determined by the Constitutional Court of Indonesia in 2010 to be concurrent with the term of office of the President of Indonesia. The current Attorney General of Indonesia Sanitiar Burhanuddin, assumed office in October 2019.

The Attorney-General's Office headed the entire Indonesian Public Prosecution Service, with a nation-wide jurisdiction. Subordinated directly under it is the Office of the High Prosecutors, based in the provincial capital, with province-wide jurisdiction.

In accordance with Attorney General Decree No 3./2024, Indonesian Public Prosecution Service consisted of:

The Attorney General’s Office of Indonesia has been the subject of several controversies relating to its internal practices, public perception, and alleged operational conduct. Several reports stated irregularities in tender and non-tender procurements by the AGO, such as several high-value contracts without competitive bidding to a single private company for digital systems described as capable of automated content creation, narrative assignment, and propaganda.

In 2025, the office sanctioned over 150 prosecutors and administrative staff for misconduct as part of internal oversight efforts, drawing attention to longstanding complaints about ethical standards and accountability in prosecutorial conduct.

The Attorney General's Office began at a time when the authority to prosecute and to adjudicate was unseparated. Its first office was shared with the first Supreme Court building complex in 2-4 Lapangan Banteng Timur street, nearby the Waterloosplein (now Lapangan Banteng, Jakarta). The building was previously used as the Hoggerechtshof te Batavia (an appellate court named the High Court of Batavia, now High Court of Jakarta), and currently it is occupied and managed by the Ministry of Finance, who also occupied and managed the Paleis van Daendels building next door.
