Hogenakkal Falls is a waterfall in South India on the Kaveri river. It is sometimes referred to as the "Niagara Falls of India," it is known for bathing areas and hired boat rides and as a major tourist attraction. Carbonatite rocks in this site are considered to be the oldest of its kind in South Asia and one of the oldest in the world.

The word Hogenakkal is formed of two Kannada words 'hoge' and 'kal'. When the water falls on the rocks it appears as if 'hoge' (smoke) is emanating from the top of the 'kal' (rock) because of the force of the water, hence Hogenakkal (smoking rocks).

It is located on the Kaveri river on the border between Dharmapuri district of Tamil Nadu and Chamrajnagar district of Karnataka.
