Mary Star of the Sea is the only studio album by American alternative rock band Zwan, released on January 28, 2003 on Reprise.

Produced by frontman Billy Corgan and Bjorn Thorsrud, the album was supported by the singles "Honestly" and "Lyric".

A deluxe edition of the album was also released, which included a bonus DVD entitled For Your Love, a 40-minute collage of interviews, studio performances, and miscellaneous footage, some of which comes from the aborted Djali Zwan album/film.
