Muhudu Maha Vihara (Sinhalaː මුහුදු මහා විහාරය) is a Buddhist temple at Pottuvil in Ampara District, Eastern province of Sri Lanka.

This temple, near a wide beach, is believed to have been built over 2000 years ago by King Kavan Tissa of Ruhuna.

[2] The ruins and remains of ancient stupas, Seema Malaka, Avasa Geya and statues can be seen at the site.

[3] According to the ancient chronicle Rajavaliya, it is stated that in the second century BC after Kelaniya was submerged by the sea due to a natural disaster, Devi the daughter of King of Kelaniya was cast to sea in a Golden Vessel to appease the gods, and washed ashore near the Muhudu Maha Vihara in Pottuwil.

Later she became the main consort of King Kavan Tissa of Ruhuna Kingdom, under the name Viharamahadevi.
