Sree Muthappan (Malayalam: ശ്രീ മുത്തപ്പന്, Kannada: ಶ್ರೀ ಮುತ್ತಪ್ಪ) is a folk Hindu deity commonly worshiped in North Malabar region of Kerala and Coorg region of Karnataka, in India. Muthappan and Thiruvappan are considered to be manifestations of Shiva and Vishnu respectively.
Worship of Muthappan is unique in that it does not follow the Satvic
Brahminical form of worship, as in other Hindu temples of Kerala. The
main mode of worship is via a ritual enactment of Muthappan, performed
daily at the Parassinikadavu
temple. Fish and toddy is used as an offering to Muthappan, and people
of all castes, religions and nationalities are permitted to enter the
temple and take part in the worship.
Muthappan is the principal deity in the ritualistic Theyyam dance (Muthappan Theyyam) performed in the famous Parassinikkadavu temple.
The ritual performers of Muthappan Theyyam belong to the Vannan
community of Kerala. The puja rituals and rites for Muthappan are
performed by the Thiyya community.
