Recent Lattice QCD results relevant for Kaon, Charm and B Physics are summarized. There is general agreement among calculations using a wide range of different lattice actions. This bolsters confidence in the lattice results and in their quoted errors. One notes considerable progress since CKM2008 in reducing lattice errors with some quantities now being calculated at the subpercent to a few percent level accuracy. Much work remains, however, and further improvements can be expected in the coming years.
