Muon reconstruction performance in ATLAS at Run-II

The ATLAS muon reconstruction has been improved for the Run-II of the LHC. In this presentation, we will discuss the new reconstruction algorithm and its latest performance measurements during the early run of the LHC in 2015 at $\sqrt{s}= 13\,$TeV using samples of $J/\psi\rightarrow \mu\mu$ and $Z\rightarrow \mu\mu$ decays. The reconstruction efficiency, transverse momentum resolution and momentum scales measurements in the various regions of the detector and for muon momenta between 4 and hundreds of GeV are presented.
