Sudar Oli (Tamil: சுடர் ஒளி Cuṭar Oḷi) is a Tamil language Sri Lankan daily newspaper published by Mass Media Syndicate (Private) Limited, part of the Uthayan Group of Newspapers.

The newspaper has been attacked several times, a number of its staff have been murdered by paramilitary groups and other forces, and it regularly receives threats.

In July 2006 Sudar Oli and Thinakkural were forced to stop distribution in Batticaloa District and Ampara District after receiving threatening phone calls allegedly from a government backed paramilitary headed by Karuna Amman.

[5][6] Vithyatharan was released on 24 April 2009 after the Colombo Crimes Division informed the court that there was no evidence connecting him to the air raid.

[7][8] Vithyatharan alleged that he had been detained in order to prevent him highlighting the plight of the civilians in the Vanni.
