"Tharros I Alitheia" (Greek: "Θάρρος Ή Αλήθεια"; English: Courage or truth, or more loosely translated as truth or dare) is a song by Greek pop singer Tamta, featuring fellow Greek pop/rock singer Sakis Rouvas. The dance song was written by Dimitris Kontopoulos with lyrics by Viki Gerothodorou for her third studio album of the same name and was released on 9 December 2009 to radio stations in Greece and Cyprus by Minos EMI. This was Tamta and Rouvas' second collaboration after a duet recorded for the latter's 2006 album was never released. The song also served as promotion for the two artists' winter 2009–2010 concert series at The S Club.
