  These are the proceedings of the "Workshop on Precision Measurements of
alphas" held at the Max-Planck-Institute for Physics, Munich, February 9-11,
2011. The workshop explored in depth the determination of alphas(mZ) in the
MS-bar scheme from the key categories where high precision measurements are
currently being made, including DIS and global PDF fits, tau-decays,
electroweak precision observables and Z-decays, event-shapes, and lattice QCD.
These proceedings contain a short summary contribution from the speakers, as
well as the lists of authors, conveners, participants, and talks.
