Toh Chin Chye DUNU (10 December 1921 – 3 February 2012) was a Singaporean statesman and academic. He was a founding member of the People's Action Party (PAP), the dominant political party in Singapore since independence. Toh played a significant role in Singapore's early political development and was instrumental in shaping the country's post-independence governance. Toh is widely recognised as one of the founding fathers of modern Singapore.

Toh served as Deputy Prime Minister from 1959 to 1968, holding other key cabinet positions including Minister for Science and Technology between 1968 and 1975 and Minister for Health from 1975 to 1981. Alongside his ministerial roles, he was Chairman of the PAP from 1954 until 1981, as well as Leader of the House from 1959 to 1968. His contributions extended into academia, serving as Vice-Chancellor of the University of Singapore (now the National University of Singapore) between 1968 and 1975.

Toh served as the Member of Parliament (MP) for the Rochore Constituency throughout his political life from 1959 to 1988. After resigning from the Cabinet in 1981, Toh continued as an MP on the backbenches. During this period, he became known for his candid criticism of his own political party.
