Daeboreum (Korean: 대보름; lit. Great Full Moon) is a Korean holiday that celebrates the first full moon of the new year of the lunar Korean calendar. This holiday is accompanied by many traditions.

The record about the origin of Daeboreum is recorded in the book Samguk yusa, where it says that a crow led the 21st King of Silla, Soji to shoot the geomungo (a Korean instrument) case, which was actually where a monk and the royal concubine were committing adultery. After this happening, on the first day of the pig, rat and horse years, people had behaved prudently, and also the 15th of January was called 'Ohgiil' (오기일; 烏忌日) and offered sacrifice to heaven this day. Also the origins of Daeboreum can be recognized by some customs listed in books, such as Samguk sagi and Silla-bongi (신라본기; 新羅本記), describing of lantern lighting. The lantern lighting custom in Daeboreum was inherited constantly; Annals of the Joseon Dynasty, the book of Taejong, 13th year has the record about the same custom clearly.

The traditional foods of Daeboreum have a lot of connections with superstition.
