In nuclear physics, the quark-meson coupling model is an effective field theory of nuclei where effective meson-fields are coupled to quark fields.

This is on contrast to quantum hadrodynamics of the form of baryon chiral perturbation theory, such as the Walecka model, where the effective fermion fields are instead the baryons (i.e. the confined bound states of three constituent quarks) with no isolated quarks appearing explicitly.
