  The top quark mass measurements are based either on a direct kinematic
reconstruction of the top quark decay products or on indirect measurements,
where an observable sensitive to the top quark mass, such as the production
cross section, is used to infer it. The ATLAS and CMS collaborations have
measured the top quark mass using various methods with increasing precision.
Recent measurements using 13 TeV pp collision data recorded at the LHC are
presented in this review.
