Mahendra Siregar[a] (born 17 October 1962 in Jakarta) is the chief of the Financial Services Authority (OJK) of Indonesia.

[3] A summary of Mahendra Siregar's work with the government is as follows: Following Mahendra's appointment as deputy minister of foreign affairs in October 2019, it was reported that President Jokowi had indicated that he should take on two main tasks: concluding trade negotiations with the United States on specific matters and taking steps to support the Indonesian palm oil industry.

Outlining his duties to the media, Mahendra noted a US review of the Generalized System of Preferences was underway and that Indonesia's involvement would need immediate attention.

Mahendra said that his second main task would focus on "neutralizing the EU's unfriendly position" on the palm oil industry in Indonesia.

Earlier in the year, in March, the EU had decided to phase out the use of palm oil by 2030 because of deforestation concerns.
