AB - This paper presents the muon momentum calibration and performance studies for the ATLAS detector based on the pp collisions data sample produced at √s=13 TeV at the LHC during Run 2 and corresponding to an integrated luminosity of 139 fb<sup>−1</sup>. An innovative approach is used to correct for potential charge-dependent momentum biases related to the knowledge of the detector geometry, using the Z → μ<sup>+</sup>μ<sup>−</sup> resonance. The muon momentum scale and resolution are measured using samples of J/ψ→ μ<sup>+</sup>μ<sup>−</sup> and Z → μ<sup>+</sup>μ<sup>−</sup> events. A calibration procedure is defined and applied to simulated data to match the performance measured in real data. The calibration is validated using an independent sample of Υ→ μ<sup>+</sup>μ<sup>−</sup> events. At the Z (J/ψ) peak, the momentum scale is measured with an uncertainty at the 0.05
