The astrophysical problems that can be attacked via proper motions in star clusters are set forth and current techniques and opportunities are described. Cluster membership work continues to progress with recent work mixing plates from various telescopes, including large reflectors. More and better internal motion studies are needed to have a significant impact on the dynamical models. Absolute proper motions of clusters present a very difficult problem, but for globulars, at least, the data are desperately needed.
