Odanad (Malayalam: ഓടനാട്, ōṭānāṭŭ, also known as Onattukara, Onad, Kayamkulam, Kallikoilon and Chirava Svaroopam) was a feudal state in late medieval Kerala. It was established in the 11th century, and disestablished in 1746 when it became part of Travancore after Venad King Marthanda Varma's northern expedition. At the time of its dissolution, it was composed of the present-day taluks of Mavelikkara, Karthikapally, Chenganur in the Alappuzha district and Karunagapally in the Kollam district.
