A simple scheme to create a macroscopic Einstein-Podolsky-Rosen (EPR) correlated atomic state is proposed and analyzed. Such a state possesses a nonlocal entanglement and is maximally squeezed, in the sense that the fluctuations of the z component of its quasispin vanish. The study shows that an elongated spinor condensate with large aspect ratio and large energy difference between spin-0 and spin-(±1) states is the best candidate to create such a state. The correlations between the atomic ensembles arise from the nonlinear atom-atom interaction among the condensate atoms.
