The National Liberation Day of Korea is a public holiday celebrated annually on 15 August in both South and North Korea. It commemorates the day when Korea was liberated from 35 years of Japanese colonial rule by the Allies in 1945. The day also coincides with the anniversary of the founding of South Korea in 1945.

In South Korea, it is known as Gwangbokjeol (Korean: 광복절; lit. The Day the Light Returned). The name Gwangbokjeol uses the term “restoration” (복; bog) instead of “independence” (독립; dongnip) to emphasize that Korea had been independent for years prior to Japanese rule.
