Salt to the Sea is a 2016 historical fiction young adult novel by Ruta Sepetys. It tells the story of four individuals in World War II who make their way to the ill-fated MV Wilhelm Gustloff. The story also touches on the disappearance of the Amber Room, a world-famous, ornately decorated chamber stolen by the Nazis that has never been recovered.

Sepetys was awarded the 2017 Carnegie Medal, the UK's most prestigious children's book award, for Salt to the Sea.
