Aththa (Sinhala: ඇත්ත, 'Truth') was a Sinhala-language daily newspaper, published from Colombo by the Communist Party of Sri Lanka between 1964 and 1995.

But the style of journalism and coverage of day-to-day affairs were also notably different from other contemporary publications, and won respect well beyond the party ranks.

Ratnaweera explained that the newspaper was successful because: "[u]nlike many bourgeois publications with their pseudoscholarly and grandiloquent style, Aththa speaks in the simple, direct and pithy language of workers.

At the time, Aththa was controlled by the faction inside the Communist Party which was critical of the United Front coalition.
