The term ''nautical publications'' is used in maritime circles to describe a set of publications, generally published by national governments, for use in safe navigation of ships, boats, and similar vessels.

The nature of waterways described by any given nautical publication changes regularly, and a mariner navigating by use of an old or uncorrected publication is courting disaster. Every producer of nautical publications also provides a system to inform mariners of changes that affect the chart.  In the United States, corrections and notifications of new editions are provided by various governmental agencies by way of [[Notice to Mariners]], [[Local Notice to Mariners]], [[Summary of Corrections]], and Broadcast Notice to Mariners.  Radio broadcasts give advance notice of urgent corrections. For ensuring that all publications are fully up-to-date, similar methods are employed as for nautical charts. Various and diverse methods exist for the correction of electronic nautical publications.
