The Indonesian Socialist Youth (Indonesian: Pemuda Sosialis Indonesia, Pesindo) was a youth-based paramilitary organisation that embraced the principles of socialism to uphold the Republic of Indonesia based on popular sovereignty. Pesindo was particularly closely associated with youth leaders in 1945. The role of youth figures such as Wikana and Chaerul Saleh (Menteng 31 Group and Kaigun Group which later merged into API Jakarta), Soemarsono and Krissubanu (PRI Surabaya), Ibnu Parna (AMRI Semarang) and other figures shaped Pesindo's identity, namely a revolutionary youth organisation against colonialism and fascism.
