  We present a summary of results from studies of quantum chromodynamics at the
Fermilab Tevatron collider by the CDF and the D0 experiments. These include Run
II results for the time period up to the end of Summer 2014. A brief
description of Run I resultsis also given. This review covers a wide spectrum
of topics, and includes measurements with jet and vector boson final states in
the hard (perturbative) energy regime, as well as studies of soft physics such
as diffractive and elastic scatterings, underlying and minimum bias events,
hadron fragmentation, and multiple parton interactions.
