KAJ is a Finnish-Swedish comedy group and music act from Jakobstad, Finland, consisting of Kevin Holmström, Axel Åhman, and Jakob Norrgård – whose initials form the name KAJ.

The group is known for their humorous and charmingly witty songs in dialect, often with themes from Ostrobothnia and Finnish-Swedish life. Their breakthrough came in 2013 with the song *“Kom ti byin”*, and since then, they have released several popular tracks such as *“Pa to ta na kako”* and *“Dom dom dom”*. KAJ blends music, sketches, and theater in their performances and has become a beloved part of Finnish-Swedish culture.
