Suharto was born on 8 June 1921 in a plaited-bamboo-walled house in the hamlet of Kemusuk, a part of the larger village of Godean, then part of the Dutch East Indies. The village is 15 kilometres (9 mi) west of Yogyakarta, the cultural heartland of the Javanese. Born to ethnic Javanese parents, he was the only child of his father's second marriage. His father, Kertosudiro, had two children from his previous marriage and was a village irrigation official. His mother, Sukirah, a local woman, was distantly related to Hamengkubuwana V by his first concubine.

Five weeks after Suharto's birth, his mother suffered a nervous breakdown; he was placed in the care of his paternal great-aunt, Kromodirjo as a result. Kertosudiro and Sukirah divorced early in Suharto's life and both later remarried. At the age of three, Suharto was returned to his mother, who had married a local farmer whom Suharto helped in the rice paddies. In 1929, Suharto's father took him to live with his sister, who was married to an agricultural supervisor, Prawirowihardjo, in the town of Wuryantoro in a poor and low-yielding farming area near Wonogiri. Over the following two years, he was taken back to his mother in Kemusuk by his stepfather and then back again to Wuryantoro by his father.

Prawirowihardjo took to raising the boy as his own, which provided Suharto with a father-figure and a stable home in Wuryantoro. In 1931, he moved to the town of Wonogiri to attend the primary school, living first with Prawirohardjo's son Sulardi, and later with his father's relative Hardjowijono. While living with Hardjowijono, Suharto became acquainted with Darjatmo, a dukun ("shaman") of Javanese mystical arts and faith healing. The experience deeply affected him and later, as president, Suharto surrounded himself with powerful symbolic language. Difficulties in paying the fees for his education in Wonogiri resulted in another move back to his father in Kemusuk, where he continued studying at a lower-fee Muhammadiyah middle school in the city of Yogyakarta until 1939.

Like many Javanese, Suharto had only one name. Religious contexts in recent years has sometimes called him as "Haji" or "el-Haj Mohammed Suharto", but these names were not part of his formal name or generally used. The spelling "Suharto" reflects modern Indonesian spelling, although the general approach in Indonesia is to rely on the spelling preferred by the person concerned. At the time of his birth, the standard transcription was "Soeharto", but he preferred the original spelling. The international English-language press generally uses the spelling 'Suharto' while the Indonesian government and media use 'Soeharto'.

Suharto's upbringing contrasts with that of leading Indonesian nationalists such as Sukarno in that he is believed to have had little interest in anti-colonialism, or political concerns beyond his immediate surroundings. Unlike Sukarno and his circle, Suharto had little or no contact with European colonisers. Consequently, he did not learn to speak Dutch or other European languages in his youth. He learned to speak Dutch after his induction into the Dutch military in 1940.
