Arunagirinathar was a Tamil great saint-poet who lived during the 15th century in Tamil Nadu, India. He was the creator of Tiruppugazh, a book of poems in Tamil in praise of the Hindu God Murugan.

His poems are known for their lyricism coupled with complex rhymes and rhythmic structures. In Thiruppugazh, the literature and devotion has been blended harmoniously.The other works of Arunagirinathar include Tiruppukal, Thiruvaguppu, Kandar Alankaram, Kandar Anubhuti, Kandar Andhadi, Vel Viruttam, Mayil Viruttam, Seval Viruttam and Tiru Elukūtrirukkai. For Muruga devotees Thiruppugazh is equivalent to Thevaram, Kandar Alankaram is equivalent to Thiruvasagam and Kandar Anubhuti is equivalent to Tirumantiram.
