Mazhuvannur Maha Siva Kshethram[1] is an ancient Hindu Temple at Tharuvana in Wayanad district of the Indian state of Kerala.

This temple is situated on the highest peak in the areas of Karingari, Paliyana, and Tharuvana.

Mazhuvannur Thekke Illam family members have been involved in leading pooja for many centuries.

Legend speaks of Lord Shiva appearing to Banasura after his arduous tapas (meditation) and offering him a wish.

Recently the temple committee has started giving "Annadanam" on the first Sunday of each month as a form of offering food to monks and other people.

The temple, which was built with bricks and wood in ancient times, was renovated recently[when?].
