The QCD sum rules for spin-dependent nucleon-nucleon (NN) and hyperon-nucleon (YN) interactions are formulated and their physical implications are clarified. A dispersion integral around the nucleon threshold can be identified as a measure of interaction strength. Calculating the operator product ex
