List of shipwrecks in the mid-Atlantic Ocean

This is a list of shipwrecks located in the main body of the Atlantic Ocean, rather than in one of its marginal seas.

For shipwrecks elsewhere in the Atlantic Ocean and its marginal seas, see List of shipwrecks in the Atlantic Ocean. This list contains shipwrecks only in the Northern Atlantic Ocean.

This is a dynamic list and may never be able to satisfy particular standards for completeness. You can help by adding missing items with reliable sources.
