Search for BSM physics including dark matter at ATLAS

The increased centre-of-mass energy of the proton-proton collisions of the LHC run 2 gives a unique opportunity to extend the sensitivity to the production of particles not foreseen by the Standard Model. This talk summarises recent ATLAS results on BSM searches. Although the focus is on searches for production of DM particles, results include searches for heavy resonances in many final states and for production of supersymmetric particles.
