Kaniyan Poongunranar, also Poongundranar or Pungundranar (Tamil: கணியன் பூங்குன்றனார், Kaṉiyan Pūngunṟanār), was an influential Tamil philosopher from the Sangam age from around 6th century BCE. His name Kaniyan implies that he was an Kaala Kanithar (astronomer) (kaala kanitham in Tamil literally means mathematics of date, time and place). Kaniyan was born and brought up in Mahibalanpatti, a village panchayat in Tamil Nadu's Sivaganga district. He composed two poems in Puṟanāṉūṟu and Natrinai.
