Kilimarathukavu Siva Parvathy Temple is a Hindu temple located in Kadakkal, Kollam, Kerala, India. It contains the largest cult image of 'Dharma Sastha', an epithet of Ayyappan.

Kilimarathukavu Temple is an ancient temple. It is believed that the old temple was destroyed in the past and only the idols were left behind. In the 21st century, a new temple was constructed. In 2011, the Travancore Devaswom Board oversaw the renovation with the help of the temple advisory committee.

During Pandava's exile in the forest, Arjuna traveled as an ascetic of Lord Shiva to seek Pashupatastra. One day during the journey, he came across a bird, which he began to follow. After several days it reached a valley, where it sat on a tree called Kilimaram near to a clean stream. Arjuna approached the bird. The bird plucked three leaves from the nearby Koovalam tree, and Arjuna felt like he was asked to increase his asceticism for Lord Shiva. Arjuna took bath in pond nearby and worshiped the Shiva lingam stone he found there. As time went on, Arjuna's asceticism became severe.

As requested by Parvati, Shiva came to Arjuna as a tribal man and Parvati as a tribal woman. An Asura (monster) in the form of a pig, was sent by Duryodhana came to kill Arjuna. Arjuna, and Shiva in his disguise, shot the monster with arrows. During the ensuing argument, Arjuna beat the tribal man with his bow. Parvati stopped him and revealed the man's true identity. Hearing this, Arjuna did Sashtanga Namaskara and Shiva gifted him Pashupatastra and gave him blessings. Several other deities, including Ganapathy, Murugan, Shastha, and Anjaneyan burst into the scene as well. Shiva told Arjuna "the place where we are now is very sacred and whoever came here for prayer should be blessed," and then disappeared. A Shivalingam appeared where he had stood.

The temple has two Shiva deities: Shiva and Mahanadan. Other deities worshipped are Parvati, Murugan, Shastha, Hanuman (Murugan), Ganapathi, Nāgathara, and Navagraha.

In the main Garbhagriha there are images of Shiva and Parvati.

The temple for Hanuman is situated in the middle of the temple pond.

The temple for Navagraha finished construction in 2021. Its elliptical shape is meant to invoke the Milky Way galaxy.
