A. P. Udayabhanu (1 October 1915 – 15 December 1999) was an Indian freedom fighter, politician, journalist, writer, and social activist from the state of Kerala.

Udayabhanu was born on 1 October 1915 to Komath Kunhiraman Channar and Alummoottil Narayani Channatti, in Muttom near Haripad of Central Travancore.

A prolific speaker, he rose to the leadership of the party very quickly: Udayabhanu was first elected to the Travancore Legislative Assembly on the Congress ticket in 1944, at the age of 29;[7] then again in 1948, this time as general secretary.

[10] The report put forth recommendations — which subsequent governments took up to varying extents — that any prohibition should be introduced gradually, and that consumption of drinks with lower alcohol content should be encouraged over stronger beverages.

[2] Between 1961 and 1978, Udayabhanu served on the editorial board of Mathrubhumi, one of Kerala's major morning dailies, and was noted for his distinct writing style.

[4] Along with autobiographical anecdotes, some of his writing included social critiques arising from issues of caste and religion, as well as satirical examinations of corruption and government.

Works such as Saṃsārikkunna daivaṃ, Ānayuṃ alpaṃ teluṅkuṃ, Koccucakkaracci, and Arthavuṃ anarthavuṃ helped him gain prominence as a writer of eminence in Malayalam.
