The Turvashas (Sanskrit: तुर्वश, Turvaśa) were one of the five major Rig Vedic tribes (panchajana, panchakrishtya or panchamanusha) mentioned in the Rig Veda and later texts. They lived southeast of the Sarasvati river region. They are one of the Rigvedic tribes.
According to the Puranas dynasties of the South India,including the Cholas, Pandyas, Cheras have descended from the Turvashas.
