Kodavatiganti Kutumba Rao (28 October 1909 – 17 August 1980), also known as Ko Ku, was an exponent of the Telugu literature in the 20th century.
His elder brother Venkatasubbiah (out of touch since 1921) was a poet-writer and he was introduced to the literary community early through him.
During this time, he published his first works: an essay called Cinema (1930) in the oriental weekly and Pranadhikam (1931), which won him the first prize in Gruhalakshmi.
His elder brother Kodavatiganti Venkatasubbaya was also a great essayist, and was also a member of 'Sahiti Samiti' because of which he was familiar with literature.
Ampakalu Kodavatiganti Kutumbarao believed in the power of scientific method and materialism in solving the problems of humanity.
