Kian Kok Middle School (Sekolah Menengah Kian Kok in Malay, 沙巴建国中学 in Chinese) is a private high school located in Kota Kinabalu, Sabah, Malaysia. The current principal is Mr. Goh Teck Seng. The school offers both Malaysian public examination, PT3 and SPM, and UEC (Unified Examination Certificate).
Kian Kok Middle School was founded in Kota Kinabalu during the early 1963. It was initially founded with the intention of accommodating junior high school students who failed to enroll into any public school. On 1 June 1963, the Hokkien association of Kota Kinabalu initiated the funding campaign for Kian Kok Middle School, with an initial donation of RM10,000 by the chairman. Within 9 months, the association has raised a total amount of approximately RM300,000.
During the early days of the school, there were only around 60 students and two classes. Students were forced to study in a temporary “campus” made up of several commercial offices that were leased by local businesses. The first building of Kian Kok Middle School was finally completely in January 1965. All 366 junior high school students enrolled in the school at that time were moved to the new permanent campus in Jalan Tuaran.
Kian Kok Middle School introduced their senior high school class in 1966. By 1968, the school was completed with four senior high school classes and eleven junior high school classes. It was considered as the standard size of a Malaysian high school at that time.
The school offers hostel facility where students can accommodate and stay within the school compound during their studies.
