In this paper, we suggest how a constituent-quark description of hadrons may be obtained from a Hamiltonian lattice formulation of QCD. By treating the quark kinetic energy part of a lattice QCD Hamiltonian perturbatively, we extract an effective Hamiltonian for mesons in the space of {ital q{bar q}} states to order 1/({ital ma}){sup 2}. Although this approach can only strictly be justified for quarks heavy compared with the QCD scale, it may nonetheless provide a qualitatively reasonable picture of light quarks in hadrons.
