In celebrating a half century history of the Korean Geographical Society, this paper is concerned about research trends of the urban geography in Korea by reviewing of 449 papers and 15 books mainly in an urban geography field. The findings are summarized as follows: (1) The development of the urban geography in Korea has several stages; circled1 The launching stage just after 1945; circled2 the premature stage in the 1960s; circled3 the taking-off stage in the 1970s; circled4 the maturing stage in the 1980s; and circled5 culminating stage in the as of 1990s. (2) The earlier studies had a few limited research themes without major debating issues. In the 1970s, various research themes had been introduced in the urban geography. More diverse themes have been studied in urban geography after the 1980s. The major themes in the urban geography included urbanization, urban structure, urban system, urban economic structure and so on. (3) The most frequent research area for the Korean urban geographers has been the Seoul metropolitan area followed by Kyongsang-Province region. Outside Korea, the most frequent research areas are the American cities followed by the cities of Japan, Canada, and France. (4) The urban geography in Korea has played a major role in introducing the quantitative methods and techniques into geography. For example over 30.5% out of papers in urban geography has taken the quantitative techniques in the past 35 years during the 1960-1994 period. The papers inside urban geography have counted more than 60 percent from research papers in major university journals and took 34.6 percent from the papers of the Journal of Korean Geographical Society.
