What we are learning about the Quark Structure of Hadrons from Lattice QCD?

Developments in lattice field theory and computer technology have led to dramatic advances in the use of lattice QCD to explore the quark structure of hadrons. This talk will describe selected examples, including structure functions, electromagnetic form factors, the nucleon axial charge, the origin of the nucleon spin, the transverse structure of the nucleon, and the nucleon to Delta transition form factor.
