Lee Kuan Yew, Honorary GCMG, Honorary CH (Chinese: 李光耀; pinyin: Lǐ Guāngyào; POJ: Lí Kng-iāu; born 16 September 1923; also Harry Lee Kuan Yew and Lee Kwan-Yew) was the first Prime Minister of the Republic of Singapore, from 1959 to 1990.

As co-founder and first secretary-general of the People's Action Party (PAP), he led the party to a landslide victory in 1959, oversaw the separation of Singapore from the Federation of Malaysia in 1965 and its subsequent transformation from a relatively underdeveloped colonial outpost with no natural resources into a stable, First World Asian Tiger. He has remained one of the most influential political figures in South-East Asia.

Under the administration of Singapore's second prime minister, Goh Chok Tong, he served as Senior Minister. He currently holds the post of Minister Mentor, a post created when his son, Lee Hsien Loong, became the nation's third prime minister on 12 August 2004.
