The AdS/CFT correspondence identifies the coordinates of the conformal boun
dary of anti-de Sitter space with the coordinates of the conformal field th
eory. We generalize this identification to theories formulated in superspac
e. As an application of our results, we study a class of Wilson loops in N
= 4 super-Yang-Mills theory. A gauge theory computation shows that the expe
ctation values of these loops are invariant under a local k-symmetry, excep
t at intersections. We identify this with the k-invariance of the associate
d string worldsheets in the corresponding bulk superspace.
