Matangi (Sanskrit: मातङ्गी, Mātaṅgī) is a Hindu goddess. She is one of the Mahavidyas, ten Tantric goddesses and an aspect of Devi, the Hindu Divine Mother. She is considered to be the Tantric form of Sarasvati, the goddess of music and learning. Like Sarasvati, Matangi governs speech, music, knowledge and the arts. Her worship is prescribed to acquire supernatural powers, especially gaining control over enemies, attracting people to oneself, acquiring mastery over the arts and gaining supreme knowledge.

One of the forms of Matangi, is often associated with pollution, inauspiciousness and the periphery of Hindu society, which is embodied in her most popular form, known as Uchchhishta-Chandalini or Uchchhishta-Matangini. She is described as an outcaste (Chandalini) and offered left-over or partially eaten food (Uchchhishta) with unwashed hands or food after eating, both of which are considered to be impure in classical Hinduism.
