They returned yesterday under an ongoing UN refugee agency programme. Over 5,000 refugees have already returned to the country under the UNHCR programme.
Under the programme, the UN body offers cash grants to returnees as livelihood support.
Over 100,000 Sri Lankan refugees were housed in Tamil Nadu.
The refugees had fled the country due to the outbreak of violence in the north and east provinces during nearly three-decade long civil war.
Some of them have lived in refugee camps since 1990.
However, with the end to the conflict in 2009 more and more have shown willingness to return, officials said.
