Since 1993 The Art Museum of Kajaani (Kajaanin taidemuseo) has operated in the city. The collection of the museum centers on Finnish modern art.
The Kajaani Town Theatre Kajaanin kaupunginteatteri was established in 1969 and is one of the most respected theaters in Finland. It was chosen as the Theatre of the Year in 2003 and continues to attract ambitious actors and theatre directors, as well as a wealth of audience from across Finland. As the leading theatre in the Kainuu district, every year the Kajaani Town Theatre goes on the road to tour neighboring towns and villages, and has been known occasionally to find its way to Southern Finland as well.
The most notable annual cultural events in Kajaani are Kajaanin Runoviikko (The Kajaani Poetry Week), originally known as Sana ja Sävel, and Kainuun JazzKevät (The Kainuu Jazz Spring)
