Methods to measure the sparticle masses with the ATLAS detector at the LHC are reported. The supersymmetric phenomenology is first briefly discussed in the context of the mSUGRA constrained model. Many examples of recent studies aiming at measuring the sparticle masses are then described. Most of these examples are based on recent full simulation of the ATLAS detector.
