Kallukkavu Vishnu temple is located on the Guruvayur – Althara road in Thrissur district, Kerala. As the temple is known as Kavu, it is believed that initially the temple must have been dedicated to Ayyappan or Bhagavathi. Now the main murti worshipped in the temple is Mahavishnu. There are no Upa Devatas.
The temple belonged to Panangattu Mana. Now the shrine is maintained by a committee formed by the villagers.
