The Royal Asiatic Society Korea Branch is a learned society based in Seoul, South Korea. First established in 1900, it was founded to provide a platform for scholarly research on the history, culture and natural landscapes of the Korean Peninsula. It is thought to be the oldest English-language academic organization now existing that is devoted exclusively to the discipline known as Korean studies. Its annual journal, Transactions, has been described as being "for much of the 20th century, the most important Western-language source on Korean culture."
