The chiral-odd structure function h{sub 1} is expected to be measured in the polarized Drell-Yan process. We calculate two-loop anomalous dimensions for h{sub 1} in the minimal subtraction scheme. Dimensional regularization and the Feynman gauge are used for calculating the two-loop contributions. Our results are important in studying the Q{sup 2} dependence of h{sub 1}. {copyright} {ital 1997} {ital The American Physical Society}
