Kim Ung-Yong (born March 7, 1963) is a Korean former child prodigy. He scored a 210 IQ on the Stanford-Binet test according to the Guinness Book of World Records. He began to learn differential calculus at the age of three. He was able to read and write in Japanese, Korean, German, and English by his fourth birthday. At the age of four, on November 2, 1967, he solved complicated differential and integral calculus problems on Japanese television, demonstrated his proficiency in German, English, Japanese, and Korean, and composed poetry.

Kim was a guest student of physics at Hanyang University from the age of three until he was six.[1]. At the age of seven he was invited to the United States by NASA.[1]. He finished his university studies, eventually getting a Ph.D in physics at Colorado State University [1] before he was 15. In 1974, during his university studies, he began his research work at NASA[1] and continued this work until his return to Korea in 1978.

When he returned to Korea, he decided to switch from physics to civil engineering and eventually received a doctorate in that field. Kim was offered the chance to study at the most prestigious universities in Korea, but instead chose to attend a provincial university.

As of 2007 he also serves as adjunct faculty at Chungbuk National University.
