  An approach is described to calculate Generalized Parton Distributions (GPDs)
in Constituent Quark Models (CQM). The GPDs are obtained from wave functions to
be evaluated in a given CQM. The general relations linking the twist-two GPDs
to the form factors and to the leading twist quark densities are recovered.
Results for the leading twist, unpolarized GPD in the Isgur and Karl model are
presented.
