Gyeongbokgung (Korean: 경복궁; Hanja: 景福宮; [kjʌŋbok̚k͈uŋ]) is a former royal palace in Seoul, South Korea. It was the first royal palace of the Joseon dynasty, having been established in 1395. It is now one of the most significant tourist attractions in the country.

The palace was among the first landmarks to be established in Seoul. It flourished under the 1418–1450 reign of Sejong the Great, who invented the native Korean script Hangul at the palace. In 1592, amidst the Imjin War, the palace was completely burned down. Plans to repair the palace fell through amidst funding shortages after the war. It would not be restored until the late 19th century, during the reign of the penultimate monarch Gojong.

In 1910, Japan colonized Korea. As the palace was a symbol of the Korean monarchy's authority, Japan systematically demolished and altered it. Almost all of its around 500 structures were sold off and demolished. In their place, modern-style buildings like the Government-General of Chōsen Building were established. Significant efforts to restore the palace began in the 1980s. Since then, the 1990–2010 First Gyeongbokgung Restoration Plan and 2008–2045 Second Gyeongbokgung Restoration Plan have attempted to restore the palace to its pre-colonial state. Dozens of buildings and structures in the palace have since been recreated, with dozens more scheduled for the future.

The palace hosts a changing of the guard ceremony twice per day. It contains the National Folk Museum of Korea and the National Palace Museum of Korea. It is accessible by the subway station Gyeongbokgung Station. For part of the year, it is open at night. Entrance is free for visitors wearing hanbok (traditional Korean clothing).
