The twist-four quark and gluon distributions in a transversely polarized nucleon are identified and relations among them are discussed by using QCD equations of motion. At the order of [ital O](1/[ital Q][sup 2]), the Drell-Yan cross section in transversely polarized nucleon-nucleon collisions is expressed in terms of these distributions.
