Maythil Radhakrishnan (born May 11, 1944), popularly known as Maythil (Malayalam മേതില്‍ രാധകൃഷ്ണന്‍), born in Alathur in Palakkad district of Kerala, is an all-rounder in Malayalam literature, being quite at home with poetry, fiction as well as non-fiction.

Maythil's first novel, Sooryavamsam, published in 1970, announced the arrival of a major talent in Malayalam literature. Four novels and many stories and poems later, his is still a fresh voice. His oeuvre reflects the whole gamut of unrelated experience—from computers to insects—that he had acquired.
