Anthe is a very small moon of Saturn between the orbits of Mimas and Enceladus. It is also known as Saturn XLIX and its designation was S/2007 S 4. It is named after one of the Alkyonides; the name means flowery.

It was found by the Cassini Imaging Team in images taken on May 30, 2007. Once the find was made, a search of older Cassini images showed this small moon in observations from as far back as June 2004. It was first announced on July 18, 2007.
