The collection of the Museum of Contemporary Art of the Repubic of Srpska consists of more than 3000 works of art and it is the most representative museum collection of this type on the territory of Bosnia and Herzegovina. Most of the artworks which are part of the collection belong to the second half of the 20th century, whilst the new acquisition policy of the Museum over the past two decades has been concentrated on contemporary art practices which had occured after the year 2000.

The basis for the formation of the Museum's collection was more than 750 works of art which were donated as part of the Solidarity Campaign by Yugoslav and Foreign Artists that was organised after a devastating earthquake which hit Banja Luka in 1969. These 800 works of art marked the starting point when it came to forming the fundus of the newly established Art Gallery. Numerous Yugoslavian artists, as well as European artists and ther colleagues from all over the word, gifted the City of Banjaluka with their works of art.

Besides the solidarity action, which continued throughout the next period of time, it is important to mention the purchasing of the artworks which were exhibited as part of the Yugoslavian art manifestation Autumn Salon, which was biennally held in the period between 1962 and 1991. Right after it was founded, the Gallery took over the organisation of Autumn Salon, and with a new, professional approach, enabled regular purchasing of artworks which were created by respectable artists not only from the region, but also from the rest of the world.

By renaming the Art Gallery into the Museum of Contemporary Art of the Republic of Srpska in 2004, new strategies and priorities related to its functioning made changes to the organisation of the fundus. In the beginnigng, the fundus was divided into three segments- Collection of Bosnian-Herzegovinian Art, Collection of Yugoslavian Art, and the Collection of Foreign Art, all of which were determined by geographical parametres. This way of organising the fundus was replaced by a more contemporary way, which now focuses on art media as the leading point in organisation of the fundus.

The Museum's fundus today is divided into four collections: Painting, Graphics and Works on Paper, Sculpture, Objects, Installations, and Media Art.
