  Measurements involving top quarks provide important tests of QCD. A selected
set of top quark measurements in CMS including the strong coupling constant,
top quark pole mass, constraints on parton distribution functions, top quark
pair differential cross sections, ttbar+0 and >0 jet events, top quark mass
studied using various kinematic variables in different phase-space regions, and
alternative top quark mass measurements is presented. The evolution of expected
uncertainties in future LHC runs for the standard and alternative top quark
mass measurements is also presented.
