Matsya is the fish avatar of the Hindu god Vishnu. Often described as the first of Vishnu's ten primary avatars, Matsya is described to have rescued the first man, Manu, from a great deluge. Matsya may be depicted as a giant fish, often golden in color, or anthropomorphically with the torso of Vishnu connected to the rear half of a fish.

Avatar is a concept within Hinduism that in Sanskrit literally means 'descent'. It signifies the material appearance or incarnation of a powerful deity, or spirit on Earth. The relative verb to "alight, to make one's appearance" is sometimes used to refer to any guru or revered human being.
