Costas Montis (Greek: Κώστας Μόντης; 18 February 1914 – 1 March 2004) was an influential and prolific Cypriot poet, novelist, and playwright.

After graduating from the Pancyprian Gymnasium, Costas Montis studied law at the University of Athens, but in 1937 on his return to Cyprus (then under British rule) he could not work as a lawyer because his degree was Greek.

The theatre closed down in 1944, and Montis returned to the school of accounting in Morphou, until in 1946 he was appointed senior editor of The Cyprus Chamber of Commerce Journal.

In support of his nomination to the Academy of Athens, Professor Nicholas Konomis stated that: With his uninterrupted literary creation of 70 years, he has been able to depict artistically the authentic rhythms, the temperature, and the action of the deepest historical and emotional fluctuations of the soul and breath of Cyprus and her people.

In his extremely powerful work he has recorded every vibration of the island (erotic, social, political), and all the thoughts of the people of Cyprus have been set down...

He has made use of the whole wealth of the linguistic, historical, and cultural tradition of greater Hellenism, and entrenched in his work, with unprecedented poetic force, the indelible character of the deep-rooted values of the Greek nation.

In her speech the Minister of Education and Culture, Claire Angelidou, said of him: "Costas Montis is not simply a great Cypriot poet.
