Māmānkam or Māmāngam was a duodecennial medieval fair held on the bank, and on the dry river-bed, of Pērār (River Nil̥a, River Ponnani, or Bhārathappuzha) at Tirunāvāya, southern India. The temple associated with the festival was Nava Mukunda Temple in Tirunavaya. It seems to have begun as a temple festival, analogous to the Kumbha Melas at Ujjaini, Prayaga, Haridwar and Kumbakonam.
