Lattice QCD and Heavy Quark Physics

Lattice QCD results relevant to heavy quark physics are reviewed. In particular new results will be shown that, for the first time, include dynamical quarks in the QCD vacuum which are close enough to being realistic to allow accurate extrapolation to the physical point. Agreement with experiment is found for a wide range of spectral quantities and the implications of this for hadronic matrix elements needed for the extraction of CKM elements from B factory experiments is discussed.
