The Lost Portrait, also known as Lost Painting, is a song composed by Michiru Yamane for Castlevania: Symphony of the Night. It is the background theme heard in the Reverse Caverns and the Anti-Chapel, as well as the Forbidden Library in the Reverse Castle.

A remake of this song is also heard in the 8th chapter of Castlevania: Harmony of Despair, The One Who Is Many.

A remix by Tetsuya Shibata appears in the game Super Smash Bros. Ultimate.
