Kim Jeong-ho (pen name Gosanja; 1804-1866?) was a Korean geographer and cartographer. It is believed that he walked the entire length and breadth of the Korean peninsula, through mountain and valley, in order to research and compile his magnum opus, the Daedong Yeojido, (대동여지도, 大東輿地圖) a map of Korea that was published in 1861, from which was subsequently made a single-sheet version, the Daedong Yeoji Jeondo (대동여지전도 大東與地全圖).
The events surrounding Kim's death are obscure. Following the publication of a later version of the Daedong Yeojido in 1866 Kim is not heard from again. The most prominent story goes that the Korean regent Daewongun, upon viewing the later version of Kim's great map, became incensed by its inclusion of details of a sensitive nature critical to national defense. This was in the context of French aggression against Korea and the Franco-British assault on China (the Second Opium War), and the resulting anxieties concerning foreign invasion. The Daewongun arrested, jailed, and beat Kim Jeong-ho who is thought to have died in prison. Little evidence has been found outlining the details of Kim's life and/or death.
The asteroid 95016 Kimjeongho is named in his honour.
