Message in a Bottle is a 1999 film directed by Luis Mandoki. It is based on a book by Nicholas Sparks (see Message in a Bottle) starring Kevin Costner, Robin Wright Penn, and Paul Newman. It was filmed in Maine, Chicago, and Wilmington, North Carolina in the United States.

A message in a bottle is a form of communication whereby a message is sealed in a container (archetypically a glass bottle, but could be plastic) and released into the sea or ocean. Such messages are not intended for a specific person, but to end up wherever the currents carry them. Because of their simplicity they are often associated with people stranded on a desert island, attempting to be rescued.

Message in a Bottle, the second romance novel written by American author Nicholas Sparks, exploited the common romance theme of love after grief. The story is set in the mid-late 1990s, then-contemporary Wilmington, North Carolina. The 1999 film Message in a Bottle produced by and starring Kevin Costner is based on this novel.

"Message in a Bottle" is a 1979 song by The Police, from their second album, Regatta de Blanc.
