The Regional Approach to Stockpile Reduction (RASR) is a long-term, coordinated, regional approach to address the threats posed by excess, unstable, loosely secured or otherwise at-risk stockpiles of conventional weapons and munitions in South East Europe.

RASR's ultimate goal is to contribute to regional security by working to prevent disastrous explosions and destabilizing diversions of stockpiled conventional weapons and ammunition.

Since 2017, RASR is being funded by the European Union through its Council Decision 2016/2356/CFSP adopted on 19 December 2016.
