Jaska Raatikainen (born 18 July 1979) is a Finnish musician, he is best known as the former drummer and co-founder of the melodic death metal band Children of Bodom from 1993 until his departure in 2019.

His first instrument was the piano, and during most of his childhood also played the French horn in a big band – a fact which later led him to be introduced to Alexander Kuoppala.

Jaska also provided backing vocals on the songs "Warheart", "Black Widow", and "Children of Bodom" from his band's album, Hatebreeder.

The problem, however, was that this happened three days before the start of the tour, which meant that Raatikainen had to quickly learn how to play ten of Sinergy's songs.

Raatikainen has also played in Virtuocity and Evemaster albums, but since those are both studio bands, he does not have to worry greatly about Children of Bodom's tour schedule, which already has to be calculated ahead to some extent, due to Laiho's previously active participation in Sinergy.

A year later, Raatikainen formed a side project with Norther's guitarist Kristian Ranta entitled Gashouse Garden, which has not yet been signed to any recording label.

Most of the time, he stays in single rooms in hotels and generally picks the beds on upper corners while travelling on tour buses.
