We combine two of Einstein's contributions to twentieth century physics, Bose-Einstein condensation and the Einstein-Podolsky-Rosen (EPR) paradox, to propose a test of local realism with mesoscopic numbers of massive particles. Using dissociation of a Bose-Einstein condensate of homonuclear diatomic molecules, we demonstrate that strongly entangled output atomic beams may be produced which possess nonlocal EPR correlations in particular field quadratures. These are directly analogous to the position and momentum correlations originally considered by EPR.
