 A notion of unfolding, or multiparameter deformation, of CR singularities of real submanifolds in complex manifolds is proposed, along with a definition of equivalence of unfoldings under the action of a group of analytic transformations. In the case of real surfaces in complex \(2\)space, deformations of elliptic, hyperbolic, and parabolic points are analyzed by putting the parameterdependent real analytic defining equations into normal forms up to some order. For some real analytic unfoldings in higher codimension, the method of rapid convergence is used to establish real algebraic normal forms. Table of Contents Unfolding CR singularities  Introduction
