Hinduism is one of Sri Lanka's oldest religions, with temples dating back over 2,000 years. As of 2011, Hindus made up 12.6% of the Sri Lankan population. They are almost exclusively Tamils, except for small immigrant communities from India and Pakistan.

The Eastern Province is one of the nine provinces of Sri Lanka, the first level administrative division of the country. The provinces have existed since the 19th century but did not have any legal status until 1987 when the 13th Amendment to the Constitution of Sri Lanka established provincial councils. Between 1988 and 2006 the province was temporarily merged with the Northern Province to form the North Eastern Province. The capital of the province is Trincomalee. Kalmunai is the largest and most populous city of Eastern Province.
