K.A.Keraleeyan (born: Kadayaprath Kunjappa Nambiar) (1910–1994) was one of the founder-leaders of the Communist Party of India in Kerala.
His father was Varikkara Padinjare Veettil Kunjiraman Nayanar and his mother was Kadayaprath Parvathy Amma.
When the procession in connection with the legendary Salt March started from Kozhikode to Payyanur he joined it along with P. Krishna Pillai, K.Madhavan and others.
When he was asked his name at the court as part of the official procedure he replied, Keralaeeyan (literally meaning one from Kerala) to declare his political stand and then onwards he was known by that name.
He has written a lot of articles as part of his social work in various periodicals and his autobiography is considered a valuable historical document of the socialist and Communist movement in Kerala in its nascent days.
