The Keralolpathi or KERALOLPATTI ( literally 'Kerala's Origin') is a Malayalam work that deals with the origin of the land of Kerala. Shungunny Menon ascribes the authorship of this work to Thunchaththu Ramanujan Ezhuthachan, a 17th-century scholar of the Malabar region of India. The Keralolpathi is mostly an expansion from an earlier Sanskrit work known as the Kerala Mahatmayam. That work is classed among the Hindu Puranas as an Upa Purana (or sub Purana) of the Bhoogola Purana.
