Recent measurements of the top-quark mass with the ATLAS and CMS detectors

The top-quark mass is one of the key fundamental parameters of the Standard Model that must be determined experimentally. Its value has an important effect on many precision measurements and tests of the Standard Model. In this talk, the top quark mass measurements by the ATLAS and CMS experiments are reviewed. These include measurements in two broad categories, the direct measurements, where the mass is determined from a comparison with Monte Carlo templates, and determinations that compare differential cross-section measurements to first-principle calculations. The most recent measurements performed at $\sqrt{s}= $13 TeV are presented.
