  Perturbative Quantum Chromodynamics has experienced an impressive progress in
the last few years, boosted by the requirements of the LHC experimental
program. In this contribution, I briefly review a selection of recent results
in QCD and LHC phenomenology, covering progress in parton distribution
functions, automation of NLO calculations, merging and matching at NLO, new
calculations at NNLO accuracy and their matching to parton showers, and new
developments and techniques in jet physics and jet substructure tools.
