Koodli, also spelled Kudli or Kudali, is a small historic village in Shimoga District, in the Indian state of Karnataka. It is at the sangam (confluence) of two rivers, the Tunga River and Bhadra River at nearly 1,200 metres (3,937 ft). They meet here to give rise to the Tungabhadra River, a tributary of the Krishna river. Their valleys host many architectural sites. The village was a much larger town and pilgrimage center before the 14th-century, one destroyed during the Islamic conquests of the south. Important temples and their ruins here include the Jagadguru Sri Shankaracharya Dakshinamnaya Sringeri Sharada Peetham, Sangamesvara temple, Ramesvara temple, Sri Chintamani Narasimha temple, Sringeri Vediki temple, Vishwakarma temple, Sharadamba temple, Amma Devasthana, and the Brahmeswara temple. Other scattered ruins of unknown temples are also found here.

The Tungabhadra River is a river in India that starts and flows through the state of Karnataka during most of its course, Andhra Pradesh and ultimately joining the Krishna River near Murvakonda in Andhra Pradesh
