Kalju Lepik (7 October 1920 – 30 May 1999) was an Estonian poet who lived as an exile for most of his life.
Lepik published his first poems in 1939 in Tartu students' journals Iloli and Tuleviku Rajad ('The Paths of Future').
From 1982 on, Lepik was the chairman of the Estonian Writers' Union in exile (Välismaine Eesti Kirjanike Liit).
In his later years, he gradually discarded all kinds of political motives and exalted patriotic pathos.
He is the father of the Estonian politician and diplomat Aino Lepik von Wirén (born 1961).
