Ghanam Krishna Iyar (1790–1854) was a composer of Carnatic music and was famous for his padams. Padams are expressive songs of three of more stanzas, used generally as an accompaniment to classical dance. Krishna Iyar was a student of the famous composer, Pacchimiriam Adiyappa. He was also influenced by Tyagaraja and Gopalakrishna Bharathi. The title Ghanam, which associated with music means 'deep' or 'grand', relates to his style of singing.
He met Tyagaraja and composed and sang Summa Summa Varuguma Sugam in raga Atana. Hi mudras included Muttukumaara and Velar.
