  The ATLAS and CMS Collaborations have performed a variety of measurements of
the top quark mass, taking advantage of the abundant production of top quarks
at the LHC. The most recent measurements are reported here, based on data
collected at 8 and 13 TeV, with particular emphasis on the distinction between
the so-called "direct" measurements and the "indirect" evaluations obtained
from cross sections and differential cross sections.
