Republic of Srpska Basketball Association (Serbian: Košarkaški savez Republike Srpske - KSRS) appeared in November 1992, after Republic of Srpska had been formed. During 1993, KSRS worked on organising what is now RS Basketball Championship. After the war on the BiH territory, KSRS integrated together with KSFBiH and KSHB into BiH Basketball Association. At the national level Republic of Srpska played friendly matches within a traditional manifestation called Basketball Tournament (Košarkaški sabor) where Republic of Srpska senior team played friendly matches against Serbian national team consisting of players from Serbian Top Division. During that tournament KSRS named the best male and female basketball players of the year.
During the International Sport Fair in Belgrade in November 2014, the protocole of cooperation was signed by BF Serbia and BF Republic of Srpska. In 2015 the Serbian selection is going to play against the Republic of Srpska during preparations for 2015 FIBA European championship.
