Vasuki (IAST: Vāsuki) is the second king of the nagas in Hinduism. He is described as having a gem called Nagamani (serpent's ornament) on his head. Adishesha, the first king of the serpents and the mount of Narayana, is his elder brother, and Manasa, another naga, is his sister. Vasuki is Shiva's snake, depicted around his neck. He is known in Chinese and Japanese mythology as being one of the "eight Great Dragon Kings" (八大龍王 pinyin: Bādà lóngwáng; Japanese: Hachidai Ryūō), amongst Nanda (Nāgarāja), Upananda, Sāgara (Shakara), Takshaka, Balavan, Anavatapta, and Utpala.
