Kaljo Põllu (28 November 1934 in Kopa, Hiiumaa – 23 March 2010) was an Estonian artist. In 1962 he received a diploma in glass art, and became director of art cabinet of Tartu State University; he founded the contemporary artist's group Visarid in 1966 in Tartu. In 1973 he moved to Tallinn, where from 1975 to 1996 he taught drawing in the Estonian Academy of Arts; at this point his art changed in style dramatically as he searched for influences from the ancient Finno-Ugric culture.
In 2007 the University of Tartu gave Põllu their "Contribution to Estonian National Identity" award.
There have been published approx. 30 titles on Kaljo Põllu's artwork in newspapers and journals outside Estonia.
