We summarise the presentations that were given within the Heavy Flavour Working Group at the DIS2013 conference. Among the topics that were discussed are open heavy flavour production, heavy quarkonia, rare beauty decays, top-quark physics, and heavy-flavour production in heavyion collisions. The presentations were on theoretical methods as well as on recent experimental results from HERA, Tevatron, LHC, RHIC, and the B-factories at KEK and SLAC.
