Dakota Louis Meyer is a former United States Marine. A veteran of the War in Afghanistan, he was awarded the Medal of Honor for his actions during the Battle of Ganjgal on September 8, 2009, in Kunar Province, Afghanistan. Meyer is the second-youngest living Medal of Honor recipient, the third living recipient for either the Iraq War or the War in Afghanistan, and the first living United States Marine in 38 years to be so honored.

The Battle of Ganjgal took place during the War in Afghanistan between American and Afghan forces and the Taliban in Kunar Province, Afghanistan on September 8, 2009. Complaints that the coalition casualties were avoidable and caused by a failure of the chain of command to provide fire support for the team triggered an official investigation and a series of reprimands to several US military officers. Army Captain William D. Swenson and Marine Corporal Dakota Meyer received the Medal of Honor for their actions during the battle. Meyer is the first living Marine to receive the Medal of Honor since the Vietnam War, and Swenson is the fifth living soldier and second officer to receive the Medal of Honor since the Vietnam War. Two other Marines at the battle, Staff Sgt. Juan Rodriguez-Chavez and Capt. Ademola Fabayo, received the Navy Cross.
