Ambalangoda-Balapitiya electoral district was an electoral district of Sri Lanka between August 1947 and March 1960. The district was named after the towns of Ambalangoda and Balapitiya in Galle District, Southern Province. The electorate was a two-member seat. The 1978 Constitution of Sri Lanka introduced the proportional representation electoral system for electing members of Parliament. The existing 160 mainly single-member electoral districts were replaced with 22 multi-member electoral districts.[1] Ambalangoda-Balapitiya electoral district was replaced by the Galle multi-member electoral district at the 1989 general elections, the first under the proportional representation system.
