Daegu (Korean: [tɛ̝.ɡu], 대구, 大邱, literally 'large hill', 대구광역시), formerly spelled Taegu and officially known as the Daegu Metropolitan City, is a city in South Korea. It is the third-largest urban agglomeration in South Korea after Seoul and Busan; it is the third-largest official metropolitan area in the nation with over 2.5 million residents; and the second-largest city after Busan in the Yeongnam region in southeastern Korean Peninsula. It was overtaken by Incheon in the 2000s, but still it is said to be the third city, according to the "Act on the Establishment of Daegu City and Incheon City" (Act No. 3424 and April 13, 1981). Daegu and surrounding North Gyeongsang Province are often referred to as Daegu-Gyeongbuk, with a total population over 5 million.
