  We present a large new family of Wilson loop operators in N=4 supersymmetric
Yang-Mills theory. For an arbitrary curve on the three dimensional sphere one
can add certain scalar couplings to the Wilson loop so it preserves at least
two supercharges. Some previously known loops, notably the 1/2 BPS circle,
belong to this class, but we point out many more special cases which were not
known before and could provide further tests of the AdS/CFT correspondence.
