Viljo Lennart Kajava (22 September 1909 – 2 February 1998) was a Finnish poet and writer.

Kavaja's Tampereen runot ("Poems of Tampere 1918") has become a symbol of the pacifistic point of view of the Finnish Civil War.

The Winter War between 1939 and 1940 was a major transformation for Kajava, and he moved from sociality to nature and impressionist lyrics in his production.

During the Continuation War, Kajava served as a front correspondent in the TK company.
