São Mathias also known as Malar is a village on Divar Island, Tiswadi or Ilhas, in the Indian state of Goa.

The Konkan Railway passes through São Mathias, the nearest stop on the mainland is the train station at Carambolim.

São Matias is surrounded by Piedade and Panjim towards west, Ponda towards East, Margão Taluk towards South.

The famous Bonderam festival is celebrated in São Mathias a week earlier than in Divar, at the end of August during the monsoon and attended by thousands of tourists and locals.

[1] The Potekar festival is celebrated across the island for three days before the start of Lent/Ash Wednesday, where local youths wear home made masks, costumes and cow bells, venturing around the village, receiving and demanding snacks and drinks from locals, and have licence to frighten the village children.

Since at least the establishment of the sovereignty of the Portuguese crown over the island, and the adoption of the Foral of Afonso Mexia in 1526, the traditional government of the village of São Mathias was the comunidade of Malar.

The centrality of this local government was displaced with the establishment of Indian sovereignty over the territory of Goa and the extension of the Panchayat system from India.
