Vatapi Ganapatim, also known as Vatapi ganapatim bhaje ham or Vatapi ganapatim bhaje, is a Sanskrit kriti song by the South Indian poet-composer Muthuswami Dikshitar (1775–1835), one of the "Trinity of Carnatic music". The panegyrical hymn praises Vatapi Ganapati, Ganesha (Ganapati) worshipped in a shrine in Tiruchenkattankudi in the Indian state of Tamil Nadu. The hymn is composed in Hamsadhvani raga (musical mode), however in tradition of kritis, individual performers add their own variations in the tune. Vatapi Ganapatim is described as the best-known piece of Muthuswami Dikshitar as well as one of the most popular compositions of Carnatic music (South Indian classical music school). The hymn is traditionally sung at the beginning of many Carnatic music concerts.
