Krishnarajanagara (sometimes abbreviated to K.R. Nagara) is a town in Mysore district.
Krishnarajanagara was founded between 1925s and 1930s as a new town, when a flood by river Kaveri damaged the nearby old town called Yedatore. The town was shifted to a place 3 miles south and at a higher elevation, now called Krishnarajanagara. It was named after Krisharaja Wodeyar, the maharaja of Mysore.
Krishnarajanagara is a town with broad roads. Krishnarajanagara is well connected by rail and road to places such as Mysore, Hassan and Hunsur. The famous Chunchanakatte Falls are located about 13 km from Krishnarajanagar.
To rehabilitate the residents of a water-logged Yadathore, Maharaja Nalvadi Krishnaraja Wodeyar picked the famed German architect Gustav Hermann Krumbiegel for forming a township which was inaugurated in the year 1934. Dornahalli is famous for a church located around 4 km from K R Nagara. Saligrama is famous for Yoganarasimha Swamy temple located 25km from K.R.Nagar.
