Budiman Sudjatmiko (born in Cilacap, Central Java 10 March 1970) is an Indonesian activist and politician.
He is the son of Wartono (father) and Sri Sulastri (mother). He pursued Economics at Gadjah Mada University where he immersed himself with leftist student movements and started to organize peasants movements in Java. Inspired by revolutionary movement, he dropped out of college to focus in leftist movement, and became a chairman of People's Democratic Association (Perhimpunan Rakyat Demokratik).
In 2002, after resigning from his chairman position and leaving his party, he pursued master's degree in Department of Political Studies, School of Oriental and African Studies. He continued to pursue MPhil degree in University of Cambridge.
In December 2004, he joined Indonesian Democratic Party of Struggle (PDI-P), which is one of the major political parties in Indonesia. On this movement, he commented:
Although there is still much which must be sorted out in terms of professionalism, ethics and morals, in the vision of struggle and other programs within the PDI-P, all of this is a challenge for the PDI-P to become the party of the little people.
In addition to having studied Economics at the Gadjah Mada University, Budiman has gained two prestigious master's degrees, both in International Relations, from the University of London's School of Oriental and African Studies (SOAS) and at Clare Hall, Cambridge.
He is currently the director of Res Publica Institute, an Indonesian defense think tank.
