## Abstract

We prove Nielsen realisation for finite subgroups of the groups of untwisted outer automorphisms of RAAGs in the following sense: given any graph Gamma, and any finite group G <= U0(A Gamma)<= Out 0(A Gamma), we find a non-positively curved cube complex with fundamental group A Gamma on which G acts by isometries, realising the action on A Gamma.
