The Seoul Lantern Festival is a festival held every November in Seoul in South Korea when hundreds of lanterns decorate the public recreation space of Cheonggyecheon.

The Seoul Lantern Festival started in 2009. The two-week festival starts on the Friday of the first week in November and covers downtown Seoul in sparkling lights, illuminating the city at night during the early winter. Visitors can encounter various types of lanterns from Cheonggye Plaza to Supyo Bridge (1.2 kilometers)

In 2014, the Seoul Lantern Festival changed its Korean name in 2014 to the Seoul Bitchorong Festival, but there was no change to the name in English. According to the organizing committee, it has changed the Korean name because the festival has expanded to be a combination of traditional lanterns and modern lights like LEDs.
