Somnathpur is a town located in Mysore district, Karnataka, India.

It is home of one of the greatest examples of Hoysala architecture of the Hoysala Empire. Somnathapura near Mysore houses the Kesava temple - the last great temple built by the Hoysala dynasty.

The village of Somanathapura is named after a minister by name Soma in the court of the Hoysala king Narasimha III (13th century CE), who founded it. The Kesava temple is a fantastic piece of art. It consists of three identical shrines built on a raised platform - with a common entrance chamber in an enclosed courtyard.
