This talk reviews recent lattice QCD calculations relevant for quark flavor
physics. Since lattice results must be accurate and precise to play a
definitive role in phenomenology, the focus is on unquenched results of
quantities which can be calculated most reliably.Comment: Invited talk delivered at Lattice2004(plenary), Fermilab, June 21-26,
