Jongmyo jerye (Korean: 종묘제례) or jongmyo daeje (종묘대제) is a traditional rite held for worshipping the deceased Joseon monarchs in Jongmyo Shrine, Seoul, South Korea. It is held every year on the first Sunday of May. The jongmyo rite is usually accompanied with the court music playing (Jerye-ak) and dance called Ilmu or line dance. Jongmyo jerye and jeryeak were designated as the first of South Korea's Masterpieces of the Oral and Intangible Heritage of Humanity by UNESCO in 2001.

The veneration of the dead, including one's ancestors, is based on love and respect for the deceased. In some cultures, it is related to beliefs that the dead have a continued existence, and may possess the ability to influence the fortune of the living. Some groups venerate their direct, familial ancestors. Certain religious groups, in particular the Eastern Orthodox Churches, Catholic Church and Anglican Church venerate saints as intercessors with God; the latter also believes in prayer for departed souls in Purgatory. Other religious groups, however, consider veneration of the dead to be idolatry and a sin.
