Benzaiten (弁才天, 弁財天) is the Japanese name for the Hindu goddess Saraswati.

Worship of Benzaiten arrived in Japan during the 6th through 8th centuries, mainly via the Chinese translations of the Sutra of Golden Light, which has a section devoted to her. She is also mentioned in the Lotus Sutra and often depicted holding a biwa, a traditional Japanese lute, in contrast to Saraswati who holds a stringed instrument known as a veena. Benzaiten is a highly syncretic entity with both a Buddhist and a Shinto side.

Referred to as Sarasvatî Devî in Sanskrit (meaning "Goddess Saraswati"), Benzaiten is the goddess of everything that flows: water, words, speech, eloquence, music and by extension, knowledge. The original characters used to write her name read "Biancaitian" in Chinese and "Bensaiten" in Japanese (辯才天) and reflect her role as the goddess of eloquence. Because the Sutra of Golden Light promised protection of the state, in Japan she became a protector-deity, at first of the state and then of people. Lastly, she became one of the Seven Gods of Fortune when the Sino-Japanese characters used to write her name changed to 弁財天 (Benzaiten), emphasizing her role in bestowing monetary fortune. Sometimes she is called Benten although this name usually refers to the god Brahma.
In the Rig-Veda (6.61.7) Sarasvati is credited with killing the three-headed Vritra also known as Ahi ("snake"). Vritra is also strongly associated with rivers, as is Sarasvati. This is probably one of the sources of Sarasvati/Benzaiten's close association with snakes and dragons in Japan.
According to Kōkei, Benzaiten is the third daughter of the dragon-king of Munetsuchi (無熱池; literally "lake without heat"), known in Sanskrit as Anavatapta, the lake lying at the center of the world according to an ancient Buddhist cosmological view
