S/2004 S 4 is the designation of an unconfirmed moon of Saturn announced by the Cassini Imaging Team on September 9, 2004. The moon was spotted while scientists were trying to confirm the orbit of another provisional moon, S/2004 S 3. The latter seemed to orbit just beyond Saturn's F Ring, while S 4 was sighted nearby shortly afterward, this time inside the F Ring. Since it is not certain how a moon's orbit could cross a ring, scientists are currently assuming that S 3 and S 4 are two separate objects, but the possibility that they are a single ring-crossing moon cannot yet be discounted.

Its orbital radius is 140,100 km (1) and its period 0.618 days.
