Loi Krathong[a] (Thai: ลอยกระทง, IPA: [lɔːj kràʔ tʰoŋ]) is a festival celebrated annually throughout Southwestern Tai cultures (Thailand, Laos, Shan, Tanintharyi, Kelantan, Kedah and Xishuangbanna). The name could be translated as "to float a basket", and comes from the tradition of making krathong or buoyant, decorated baskets, which are then floated on a river.
