Annamalai (IAST: Annamalai [əɾʊˈɳaːtʃələ], 'Red Mountain') is a hill in Tiruvannamalai district, Tamil Nadu, and one of the five main Shaiva holy places in South India. The Arunachalesvara Temple to Shiva is located at the base of the hill. The hill is also known by the names Annamalai, Arunagiri, Arunachalam, Arunai, Sonagiri, and Sonachalam.
Every year in the Tamil month of Kārttikai (November–December), the Kārttikai tīpam light is lit atop the hill.
It is also an important place for devotees of Ramana Maharshi, with Sri Ramana Ashram situated at its foothills.
