Contribution
It provides a comprehensive review of lattice results for heavy quark physics, including decay constants, mixing parameters, and baryon spectroscopy, with an assessment of systematic uncertainties.

Abstract
The status of lattice calculations for heavy quark systems is reviewed, focussing on weak matrix elements for leptonic and semi-leptonic decays of heavy mesons. After an assessment of the main systematic errors, results for the decay constants and , the parameter describing mixing, the Isgur-Wise function and the spectroscopy of heavy baryons are discussed.
