Municipal councils of Sri Lanka

There are 27 Municipal councils in Sri Lanka, which are the legislative bodies that preside over the largest cities and first tier municipalities in the country. Introduced in 1987 through the 13th Amendment to the Constitution of Sri Lanka, municipal councils became a devolved subject under the Provincial Councils in the Local Government system of Sri Lanka. Until 2025 municipal councils collectively governed 4.19 million people within a 698 square kilometre area. There were 445 Councillors in total, ranging from 53 to 9 per council.

Polonnaruwa Municipal Council was created on 30 June 2017, bifurcated from Thamankaduwa Pradeshiya Sabha.

A extraordinary gazette was published in 2022 to upgrade existing urban councils to municipal councils for the localities of Puttalam, Trincomalee, Vavuniya, Kegalle and Kalutara. Following the conclusion of the Local Government elections in 2025, the municipal councils for the new localities commenced operations.
