"An Ocean of Memories" is a song written by James Horner for the film Titanic that was originally meant to score Rose's memories near the end of the film. It is also featured on the film's soundtrack.

In the final film, only small parts of the song were used in the film edit of "2 1/2 Miles Down" and the opening of the cue overlapped "Unable to Stay, Unwilling to Leave" during the heaven scene.
