Relative proper motions are determined for stars brighter than B ∼ 17 m in a 1.5° × 1.5° field centered on the globular cluster 47 Tuc (NGC 104). Proper motions and membership probabilities are tabulated for 3076 stars within 32' of the cluster center. 14 astrographic plates with epoch differences up to 92 years were completely scanned, and each detectable object was stored. Proper motions were computed with an iterative central-overlap technique. The modal proper motion accuracy is 0.9 milliarcsec/year.
