Kim Ung-yong (born March 7, 1963) is a South Korean civil engineer and former child prodigy. Kim was listed in the Guinness Book of World Records under "Highest IQ"; the book gave the boy's score as about 210.  Guinness retired the "Highest IQ" category in 1990 after concluding IQ tests were too unreliable to designate a single record holder.
Kim was born in Hongje-dong, Seoul, South Korea. His father was Kim Soo-Sun, a professor. He started speaking at the age of 6 months and was able to read Japanese, Korean, German, English and many other languages by his third birthday. When he was four years old, his father said he had memorized about 2000 words in both English and German. He was writing poetry in Korean and Chinese and wrote two very short books of essays and poems (less than 20 pages).
An article was published about him in Look magazine. After reading the article, a teacher and students at Grant High School in Los Angeles began writing to him and in February 1967 his father applied for Kim to be enrolled at Grant High School.
On November 5, 1977, Kim solved complicated differential and integral calculus problems on Japanese television.
