    The concept of regular saddle surfaces is extended to simply connected 3-manifolds of constant curvature. It is proven that a regular surface in elliptic and hyperbolic three-space is a saddle surface iff its Gaussian curvature is everywhere not greater than the curvature of the surrounding space.
