We study correlations of spin currents flowing through a Coulomb blockaded quantum dot. While vanishing for elastic co-tunneling, these correlations develop as the quantum dot enters the Kondo regime. They are a manifestation of Kondo physics in quantum dots. We demonstrate that the spin current correlator is non-perturbative in the Kondo coupling.
