A '''Local Notice to Mariners''' is a [[navigation]] publication in the United States issued by each [[U.S. Coast Guard]] District to disseminate important information affecting navigational safety within that District. This Notice reports changes and deficiencies in aids to navigation maintained by the Coast Guard. Other marine information such as new [[nautical chart|charts]], channel depths, naval operations, and regattas is included. Since temporary information of short duration is not included in the weekly [[Notice to Mariners]], the ''Local Notice to Mariners'' may be the only source of such information. Small craft using the [[Intracoastal Waterway]] and small harbors not normally used by oceangoing vessels need it to keep charts and publications up-to-date.

Since correcting information for U.S. charts in the ''Notice to Mariners'' is obtained from the Coast Guard Local Notices, it is normal to expect a lag of 1 or 2 weeks for the ''Notice to Mariners'' to publish a correction from this source.

The ''Local Notice to Mariners'' may be obtained free of charge by contacting the appropriate Coast Guard District Commander. Vessels operating in ports and waterways in several districts must obtain the ''Local Notice to Mariners'' from each district. <!-- See Figure 422 for a complete list of U.S. Coast Guard Districts. provide a link instead-->
