The Marine Safety Pin is a decoration of the United States Coast Guard which is authorized to those personnel who have obtained qualifications as Coast Guard Safety Officers and Safety Observer Supervisors. To be awarded the Marine Safety Pin, a service member must complete a standard Coast Guard safety course, be qualified in emergency procedures (including CPR) and must have been passed on examination on the fundamentals of 3M (Maintenance and Material Management).

The Marine Safety Pin is considered a secondary qualification badge and is worn on the left uniform pocket, below award ribbons and warfare qualification badges. The badge may be worn in the primary position, above award ribbons, if not other warfare badges have been obtained.
