Koliakode N. Krishnan Nair is an Indian politician and a lawyer.
He represented Vamanapuram constituency in 6th, 7th, 8th, 9th and 13th Kerala Legislative Assembly.
He also serves as the member of governing committee of Pariyaram Co-operative Medical College.
In 1995, Koliakode was expelled from CPI(M) as part of disciplinary proceedings, but he rejoined the party as a primary member after the Control Commission allowed his appeal.
[2] In his autobiography, Pirappancode Murali accused Koliyakode, who is closely related to the CPM state leadership, of using that influence to avoid him from the candidature in Vamanapuram and when that failed, he tried to defeat him, but Krishnan Nair responded that the allegations leveled against him were false and baseless.
