The Gold Lifesaving Medal and Silver Lifesaving Medal are U.S. decorations issued by the United States Coast Guard. The awards were established by Act of Congress, 20 June 1874; later authorized by 14 U.S.C. § 500. These decorations are two of the oldest medals in the United States and were originally established at the Department of Treasury as Lifesaving Medals First and Second Class. The Department of the Treasury initially gave the award, but today the United States Coast Guard awards it through the Department of Homeland Security. They are not classified as military decorations, and may be awarded to any person.

The United States Life-Saving Service was a United States government agency that grew out of private and local humanitarian efforts to save the lives of shipwrecked mariners and passengers. It began in 1848 and ultimately merged with the Revenue Cutter Service to form the United States Coast Guard in 1915.
