Mohammad Guntur Soekarnoputra (born 3 November 1944), better known as Guntur Soekarnoputra or Guntur Soekarno, is an Indonesian entrepreneur best known as the eldest son of President Sukarno and Fatmawati. During his infancy, Guntur was abducted along with his parents during the Rengasdengklok Incident of 16 August 1945. In the national revolution that followed Sukarno's proclamation of Indonesian independence the following day, Guntur was entrusted to several friends of Sukarno while his father led the country. In 1949, following Dutch recognition of Indonesian independence, the family moved to Jakarta and settled at the Presidential Palace. After his parents separated in 1955, Guntur lived with Fatmawati. However, he remained involved with Sukarno, joining him on trips to the United States and Yugoslavia.
Sukarno was overthrown in 1967. After his father's death in 1970, Guntur was initially expected to continue Sukarno's political legacy. However, despite briefly campaigning for the Indonesian National Party ahead of the 1971 legislative election, he focused more on supporting his family through his construction business. Since then, Guntur has mostly avoided politics, the only one of his siblings to do so. He has written memoirs on his childhood, campaigned to rehabilitate his father's reputation, and held several photography exhibitions. His daughter Puti has served in the House of Representatives.
