We study the algebraic structure of the outer automorphism group of a general right‐angled Artin group. We show that this group is virtually torsion‐free and has finite virtual cohomological dimension. This generalizes results proved earlier by the authors and Crisp for 2‐dimensional right‐angled Artin groups.
