Abdul Razak bin Hussein (Jawi: عبد الرزاق بن حسين; 11 March 1922 – 14 January 1976) was a Malaysian lawyer and politician who served as the second prime minister of Malaysia from 1970 until his death in 1976. He also served as the first deputy prime minister of Malaysia from 1957 to 1970. He is referred to as the "Father of Development" ("Bapa Pembangunan") of Malaysia.

During his term as prime minister, Abdul Razak launched the Malaysian New Economic Policy (NEP), a program aimed at reducing the socioeconomic disparity between ethnic communities, particularly those of the ethnic Malay and Chinese. He also oversaw a realignment of Malaysia foreign policy away from his predecessor's pro-West and anti-Communist attitude and towards neutrality, with the country becoming a member of the Non-Aligned Movement in 1970. Abdul Razak was also the figure responsible for setting up Barisan Nasional (BN), a political coalition which held power uninterrupted from its inception in 1974 to 2018.

His eldest son, Najib Razak, became the sixth prime minister in 2009; however, later became infamous for his involvement in the 1MDB corruption scandal, which led to his conviction on multiple charges of corruption, abuse of power, and money laundering.

Born in Kampung Pulau Keladi, a village located northwest of Pekan, Pahang on 11 March 1922, Abdul Razak is the first of two children to Hussein Awang bin Mohd Taib (1898–1950) and Fatimah binti Daud (1906–1968). An aristocratic descendant holding the title Orang Kaya Indera Shahbandar, Abdul Razak studied at the Malay College Kuala Kangsar.

After joining the Malay Administrative Service in 1938, he was awarded a scholarship to study at Raffles College in Singapore in 1940. His studies at the college ceased with the onset of the Second World War. During the war he helped organise the Wataniah resistance movement in Pahang.

After World War II, Abdul Razak left for Britain in 1948 to study law. In 1950, he received a law degree and qualified as a barrister at Lincoln's Inn in London. During his student days in England, Abdul Razak was a member of the British Labour Party and a prominent student leader of the Malay Association of Great Britain, and formed the student association Malayan Forum.

After his studies were interrupted in 1942 because of World War II, Abdul Razak returned to Kuantan, Pahang. There, he met his former colleague from the Malay Administrative Service, Yeop Mahidin, and expressed his interest in joining the Malay Regiment (now Royal Malay Regiment). Mahidin, who was also the founder of Askar Wataniah Pahang ('Pahang State Territorial Army'; precursor of the Rejimen Askar Wataniah), recruited Razak into his new guerrilla force. Upon the completion of his training, Razak was instructed to join the Japanese Malayan Civil Service as an agent and informant.

Razak, as an aristocrat and son of a respected Malay leader in Pahang, was posted to his home state of Pahang as an assistant to District Officer and at the same time as a bridge for the Japanese to gain the trust of local Malays. Using his privileges as an aristocrat, Razak started networking with the Imperial Japanese Forces while maintaining his connection with Yeop Mahidin. His role as an informant inside the Japanese Administration was only known to a few. Because of this, Razak was labelled as a traitor by the rest of the Wataniah Pahang.
