Rotational velocities $v \sin i$ are derived for two dozen stars in each of the globular clusters M3, M13, and NGC 288. Rotation is most prevalent in M13: most stars are rotating more rapidly than 20 \kms, and a half dozen more rapidly than 30 \kms. In M3, only a few are rotating more rapidly than 20 \kms, and none reach this level in NGC 288. We illustrate our method of determining $v \sin i$ from fits to a grid of synthetic spectra, present the results for the stars observed in each cluster, and discuss the distribution of $v \sin i$ values and their ramifications for stellar evolution and the appearance of the globular-cluster color-magnitude diagram.
