Prof. Dato Sri Dr. Sim Kui Hian (; born 18 August 1965) is a Malaysian politician and cardiologist who is serving as the Deputy Premier of Sarawak and the territory's Minister of Public Health, Housing and Local Government Sarawak in the Gabungan Parti Sarawak (GPS) administration under Premier Abang Abdul Rahman Johari Abang Openg since January 2022, as well as an elected representative for the constituency of N14 Batu Kawah in the Sarawak State Legislative Assembly (DUN) since May 2016. Dr. Sim is Sarawak's first deputy premier (a title formerly known as deputy chief minister) of Chinese descent in more than a decade after George Chan Hong Nam stepped down in 2011. Previously, he served as the Minister of Local Government Sarawak from May 2016 to January 2017 under the late Adenan Satem's cabinet, and Minister of Local Government and Housing Sarawak from January 2017 to December 2021 under Abang Johari's first cabinet. He also had served as Senator in the Parliament of Malaysia from April 2014 to April 2017. Additionally, he holds a watching brief role which gives him oversight over several Malaysian federal government departments operating in the territory, namely the Sarawak Health Department and the Sarawak Fire and Rescue Department. He is a member of the Sarawak United Peoples' Party (SUPP), which he is the Party President since September 2014. He is also one of the founding Vice-Chairmen of the GPS coalition, in which SUPP is a co-founding component party. While acknowledging that Sarawak is part of Malaysia, Dr. Sim is one of the most vocal and consistent proponents for more Sarawakian autonomous power and rights, based on the unique contexts of the Malaysia's formation as originally outlined in the Malaysia Agreement 1963, Inter-Governmental Committee Report and recommendations, and the Report of the Cobbold Commission.
