Insignia and badges of the United States Marine Corps are military "badges" issued by the United States Department of the Navy to Marines who achieve certain qualifications and accomplishments while serving on both active and reserve duty in the United States Marine Corps.

In the United States (U.S.), a marksmanship badge is a U.S. military badge or a civilian badge which is awarded to personnel upon successful completion of a weapons qualification course or high achievement in an official marksmanship competition. The U.S. Army and the U.S. Marine Corps are the only military services that award marksmanship qualification badges. However, marksmanship medals and/or marksmanship ribbons are awarded by the U.S. Navy, U.S. Coast Guard, and U.S. Air Force for weapons qualifications. For non-military personnel, different U.S. law enforcement organizations and the National Rifle Association (NRA) award marksmanship qualification badges to those involved in law enforcement. Additionally, the Civilian Marksmanship Program (CMP) and the NRA award marksmanship qualification badges to U.S. civilians. Most of these organizations and the U.S. National Guard award marksmanship competition badges to the people they support who succeed in official competitions.
