Palaivananathar Temple is a Hindu temple dedicated to the deity Shiva, located in Papanasam, in Thanjavur district in the South Indian state of Tamil Nadu. Shiva is worshiped as Papanasanathar, and is represented by the lingam. His consort Parvati is depicted as Thavalavennayagal. The presiding deity is revered in the 7th century Tamil Saiva canonical work, the Tevaram, written by Tamil saint poets known as the Nayanars and classified as Paadal Petra Sthalam.

The temple complex covers around one acre and can be entered through a five-tiered gopuram, the main gateway. The temple has a number of shrines, with those of Papanasanathar and Thavalavennayagal, being the most prominent. All the shrines of the temple are enclosed in large concentric rectangular granite walls. The temple has a granary made of brick from the Vijayanagar Empire, which is maintained as a monument of the state Archeological Department.

The temple has four daily rituals at various times from 6:00 a.m. to 8:00 p.m., and four yearly festivals on its calendar. Chitra Pournami and Aani Thirumanjanam during the Tamil month of Aaani (June–July) are the most prominent festivals celebrated in the temple.

The original complex is believed to have been built by Cholas, while the present masonry structure was built by Vijayanagar kings during the 16th century. In modern times, the temple is maintained and administered by the Hindu Religious and Charitable Endowments Department of the Government of Tamil Nadu.

As per Hindu legend, Shiva is believed to have killed a tiger and worn the skin of the tiger as a sign of his victory in the forest Darukavana. At a later time, during the Mahabharat times, the Pandava prince Arjuna who was in exile along with his brothers was asked by sage Dhaumya to visit the forest and seek the blessings of Shiva. Arjuna visited the place and obtained special skills and weapons in archery from Shiva. The presiding deity is believed to have absolved the sins of various other deities namely Vishnu, Brahma, Rama, Sita, sage Vashista, Lakshmana, other celestial deities and hence got the name Papanasanathar, the one who absolves sins.
