Kauko Röyhkä, (born Jukka-Pekka Välimaa, 12 February 1959, Valkeakoski), is a Finnish rock musician, author and screenwriter.

He managed to raise some fuss in the early 1990s by claiming to be satanist (later he explained that the statement was just an experiment with publicity).

Some of the most well known songs by Röyhkä include "Lauralle", "Talo Meren Rannalla", "Paska Kaupunki" and "Paha Maa".

Röyhkä has written ten novels or short story collections and some other works including the biography of Finnish porn star Henry Saari and a book about Velvet Underground.

He has also written columns for the newspaper Kaleva and record reviews for Rytmi magazine, and been a screenwriter in four films.
