Timo Kustaa Mukka (17 December 1944 – 27 March 1973) was a Finnish author who wrote about the lives of people in Lapland.

The village had a strong presence of both Laestadianist Christians and communists, which affected the development of Mukka's worldview.

Martti Qvist had stopped replying to Mukka's subscriptions in early 1960, so when he wrote his first novel later that year he sent it to the Gummerus publishing house instead.

In the autumn of 1961 at the age of seventeen Mukka moved to Helsinki to study at the Academy of Fine Arts to become a painter.

Its two most prominent representatives were the enfants terribles of modernist Finnish literature, poet and translator Pentti Saarikoski and author Hannu Salama.

In 1973, Finnish tabloid journal Hymy published a sensationalist article on Mukka which is believed to have contributed to the deterioration of his health.

Mukka's first novel, The Earth is a Sinful Song, was in 1973 adapted into a popular movie, The Land of Our Ancestors, the first film by the Finnish director, Rauni Mollberg.
